Find the volume of a right circular cylinder of a diameter of base 14 cm and height 40cm​

Answer»

Given :

  • Diameter of BASE of CYLINDER = 14cm.
  • Height of Cylinder = 40cm.

To Find :

Solution :

\longmapsto\tt{Diameter=14cm}

\longmapsto\tt{Radius=\cancel\dfrac{14}{2}=7cm}

\longmapsto\tt{Height=40cm}

Using Formula :

\longmapsto\tt\boxed{Volume\:of\:Cylinder=\pi{{r}^{2}h}}

Putting Values :

\longmapsto\tt{\dfrac{22}{\not{7}}\times{7}\times{\not{7}}\times{40}}

\longmapsto\tt{22\times{7}\times{40}}

\longmapsto\tt\bold{6160{cm}^{3}}

So , The volume of Cylinder is 6160cm³..

_______________________

  • C.S.A of Cylinder = 2πrh
  • T.S.A of Cylinder = 2πr(r+h)
  • Volume of Cylinder = πr²h

. If twice the age of A is added to B's age, thesum is 45 and if twice the age of B is added toA's age, the sum is 30. Then the age of B is​

Answer»

Step-by-step EXPLANATION:

\bf{\underline{\underline\red{Given:-}}}

  • If TWICE the age of A is added to B's age, the
  • sum is 45.

  • If twice the age of B is added to
  • A's age, the sum is 30.

\bf{\underline{\underline\blue{To\:Find:-}}}

  • The age of B

\bf{\underline{\underline\green{Solution:-}}}

Let

The present age of B = x

And present age of A = y

According to the 1st condition:-

If twice the age of A is added to B's age, the

sum is 45

\rm \implies x + 2y = 45.....(i)

According to the 2nd condition:-

If twice the age of B is added to A's age, the sum is 30.

\rm \implies 2x + y = 30.....(ii)

Multiplying equation (i) with 2

\rm \implies 2(x + 2y = 45)

\rm \implies 2x + 4y = 90.....(iii)

Subtracting equation (ii) from (iii)

\rm \implies (2x + 4y )- (2x + y) = 90 - 30

\rm \implies 2x + 4y - 2x  -  y = 60

\rm \implies3y = 60

\rm \implies y =  \dfrac{60}{3}  = 20

Substituting y = 15 in equation (i)

\rm \implies x + 2y = 45

\rm \implies x + 2(20) = 45

\rm \implies x +40 = 45

\rm \implies x  = 45 - 5

\rm \implies x  = 5

\boxed{ \rm \therefore Present \: age \: of \: B = 5years}

X=4-√15 find x+1/x please give answer of these

Answer»

Answer:

8

Step-by-step explanation:

R.T.P {REQUIRED to prove} : X+1/x

Given x = 4-√15

1/x = 1/4-√15

It's Rationalising factor is 4+√15

So, 1/(4-√15) x (4+√15)/(4+√15)

= (4+√15)/ [(4)^2 - (√15)^2]

=(4+√15)/16-15

= (4+√15)

(4-√15) + (4+√15)

+√15 and -√15 GETS cancelled

4+4

=8

(a) If two vertices of a parallelogram are(3, 2) and ( 1, 0) and the diagonalsintersect at (2, - 5) then find the othertwo vertices.​

Answer»

Answer:

(1, - 12), (3, - 10)

Step-by-step explanation:

One of the PROPERTIES of parallelogram is "The DIAGONALS of PARALLELOGRAMS bisect each other".

The coordinates of midpoint are [(x_{1} + x_{2})/2, (y_{1} + y_{2})/2]

~~~~~~~~~~

Let A (3, 2) and B (1, 0) are two vertices of a parallelogram, and O (2, -5) is the diagonals intersect.

AO = OC

\frac{3+x}{2} = 2 ⇒ x = 1

\frac{2+y}{2} = - 5 ⇒ y = - 12

C (1, - 12)

BO = OD

\frac{1+x}{2} = 2 ⇒ x = 3

\frac{0+y}{2} = - 5 ⇒ y = - 10

D (3, -10)

Answer»

Answer:Your answer is (a) 937500

Step-by-step explanation:

25% of 10,00,000 + 10,00,000 ( FIRST 10 years)

=25/100 × 10,00,000 + 10,00,000

= 250,000 + 10,00,000

= RS 12,50,000

Again,

25% of 12,50,000 - 12,50,000 ( Next 10 years)

= 12,50,000 - 25/100 × 12,50,000

= 12,50,000 - 3,12,500= Rs 9,37,500
