Suppose you have given a circle give a construction to find its centre​

Answer»

Step-by-step explanation:

1) take any three points on the CIRCLE

2) add those points

3) it forms a triangle

4) if you SEE clearly all sides are nothing but chords of that circle

so we know a theorem that is

if a line drawn from the centre perpendicularly to a chord it will bisect the chord

so now converse of this,

if I DRAW a perpendicular BISECTOR of a chord it will passes through centre

so in order to find the centre draw any two perpendicular bisectors of two chords which are non parallel

then the point of intersection is the centre

Q.13.If the length,breadth and height of a cuboid are in the ratio5:3:2and its totalsurface area is1550sq.m. Find:(i)the dimensions of the cuboid (ii)volume of the cuboid.​

Answer»

Question:-

If the length,breadth and height of a CUBOID are in the ratio5:3:2and its total surface area is1550sq.m. Find:(i)the dimensions of the cuboid (ii)VOLUME of the cuboid.

Answer:-

  • The length, Breadth and height of cuboid is 25 m,15 m and 10 m.
  • The volume of cuboid is 3750 m³.

To find:-

  • the dimensions of the cuboid
  • volume of the cuboid.

Solution:-

  • Ratio = 5:3:2

Put x in the ratio,

  • Length = 5x
  • Breadth = 3x
  • Height = 2x
  • Total surface area = 1550 m²

(i)

\large { \mathfrak{ \green{ \underline{ \purple{ sa = 2(lb + bh + lh)}}}}}

where,

  • L = length
  • b = breadth
  • h = height

According to question,

\large{ \tt:  \implies \:  \:  \:  \:  \:  \:  \: 2(lb + bh + lh) = 1550}

\large{ \tt : \implies \:  \:  \:  \:  \: 2(5x \times 3x + 3x \times 2x + 5x \times 2x) = 1550}

\large{ \tt : \implies \:  \:  \:  \:  \: 2(31 {x}^{2} ) = 1550}

\large{ \tt : \implies \:  \:  \:  \:  \: 31 {x}^{2}  =  \frac{1550}{2} } \\

\large{ \tt : \implies \:  \:  \:  \:  \:  {x}^{2}  =  \frac{775}{31} } \\

\large{ \tt : \implies \:  \:  \:  \:  \: x =  \sqrt{25} }

\large{ \tt : \implies \:  \:  \:  \:  \: x = 5 \: m}

  • The VALUE of x is 5 m
  • Length = 5x = 5×5 = 25 m
  • Breadth = 3x = 3×5 = 15 m
  • Height = 2x = 2×5 = 10 m

The length, Breadth and height of cuboid is 25 m,15 m and 10 m.

(ii)

\large { \mathfrak{ \green{ \underline{ \purple{ volume = l \times b \times h}}}}}

According to question,

\large{ \tt :  \implies \:  \:  \:  \: volume = 25 \times 15 \times 10}

\large{ \tt :  \implies \:  \:  \:  \: volume = 3750 \:  {m}^{3} }

  • The volume of cuboid is 3750 m³.

10. Prove that the angle between the two tangents drawn from an external point to a circleis supplementary to the angle subtended by the line-segment joining the points ofcontact at the centre.​

Answer»

Answer:

Draw a circle with center O and take a external point P. PA and PB are the tangents.

As radius of the circle is perpendicular to the tangent.

OA⊥PA

Similarly OB⊥PB

∠OBP=90 o

 

∠OAP=90 o

 

In Quadrilateral OAPB, sum of all INTERIOR angles =360 o

 

⇒∠OAP+∠OBP+∠BOA+∠APB=360  o

 ⇒90o+90o+∠BOA+∠APB=360 o

∠BOA+∠APB=180 o

 

It proves the angle between the TWO tangents drawn from an external point to a circle SUPPLEMENTARY to the angle subtented by the line segment

hope it helps

Kindly solve this,Prove that in a parallelogram the inspectors of any two consecutive angles intersect at right angles.

Answer»

Hey ! Here's your answer!

To prove: In a parallelogram the inspectors of any TWO consecutive angles intersect at right angles.

Proof:

Lets CONSIDER,

  • ABCD is a parallelogram.

We know that,

  • AB || CD and AB is a transversal . . . . ( i )

Now,

As we know that, \angleADB + \angleBCD = 180° ( From ( i ) )

So,

= \dfrac{1}{2}\angleADB + \dfrac{1}{2}\angleBCD = \dfrac{1}{2} × 180

= \dfrac{1}{2}\angleADB + \dfrac{1}{2}\angleBCD = 90°

That is,

= \angle1 + \angle2 = 90 . . .(ii)

Now, in \<klux>TRIANGLE</klux>COD

= \angle1 + \angle2 + \angleCOD = 180° { Prop. of triangle }

= 90 + \angleCOD = 180°

= \angleCOD = 180° - 90

= \angleCOD = 90°

Hence Proved!!

The difference between circumference and diameter of a circle is 21.4cm find the radius​

Answer»

Given,

πr² - 2πr = 21.4

π (r² - 2r) = 21.4

r² - 2r = 21.4 × 7/ 22

r² - 2r = 6.80

r² - 2r - 6.8 = 0 (QUAD. EQN)

R = 3.792, -1.79

Since the value of radius cannot be Negative, therefore r = 3.79.

Radius = 3.79 CM

Write the laws of exponent, if x, y are positive real numbers and m, n are rational numbers. ​

Answer»

Supposed you are asked to calculate or multiply large numbers and you don’t have an electronic calculator. What if you get the wrong answer? How can we make this calculation easier? So let us TRY to understand some of the exponent rules for real numbers.

Laws of EXPONENTS or Exponent Rules

What is meant by an exponent? You must have come across the expression 3². Here 3 is the base and 2 is the exponent. Exponents are also called Powers or Indices. The exponent of a number tells how MANY times to USE the number in a multiplication. Let us study the laws of exponent. It is very important to understand how the laws of exponents laws are formulated.

Exponent Rules

(Source: math warehouse)

1. Product law

According to the product law of exponents when multiplying two numbers that have the same base then we can add the exponents

am × an= a m+n

where a, m and n all are NATURAL numbers. Here the base should be the same in both the quantities. For example,

2³ × 24 = 27
22/3 × 21/5 = 2 2/3 + 1/5 = 2(10+3)/15 . We get, = 212/15
(-6) 3 x (-6) 2 = (-6) 3+2 = (-6) 5

On certain article if rate of CGST is 8% then what is the rate of SGST? and what is the rate of GST.​

Answer»

Answer:

GIVEN:- Rate of CGST =9%

As we KNOW that,

Rate of SGST = Rate of CGST

Therefore,

Rate of SGST =9%

Rate of GST = Rate of CGST + Rate of SGST

⇒ Rate of GST =9%+9%=18%

Thus the rate of SGST is 9% and the rate of GST is 18%.

5. Is 6598 a perfect square?​

Answer»

ANSWER:

\huge\tt\underline{question}

is 6598 a perfect square?

\huge\tt\underline{answer}

No,6598 is not a perfect square

A perfect square is a number that can be expressed as the PRODUCT of two EQUAL integers.

\tt\underline\orange{try\:these\:steps\:first}:

★ A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square.

★All possible numbers that are a perfect square have a digital root of 1, 4, 7, 9.

\tt\underline\pink{why\:6598\:is\:not\:a\: perfect\: square}

the number 6598 end's with 8 ,and the numbers which end with 2,3,7,8 are not perfect square.

\bf\underline\red{perfect\: square\:of\:6598}

For finding the square root we can use the general method of division. Therefore the LEAST number to be added to 6598 would be: 6724 minus 6598 = 126 to get a perfect square.

{\orange{\boxed{\boxed{\boxed{\pink{\underline{\underline{\purple{\mathscr{perfect\: square\:of\:6958\:=\:126}}}}}}}}}}
