If the circle touches all the four sides of the square tile, find the area of theportion. In which tile, area of shaded portion will be more? (lake it = 3.14)). Find the areain the which of the tilearea of the shaded​

Answer»

Answer:

(A) The AREA of shaded PORTION is 86 cm²

(B) The Area of shaded portion is 86 cm²    

Step-by-step explanation:

GIVEN as :

(A)

A square ABCD with side length = 20 CM

Four quarter circles are drawn at each corner

From The figure

Let The area of shaded portion = A sq cm

According to question

The area of square = side²

Or, The area of square = (20 cm) ²

or, The area of square = 400 cm²

Again

Area of circle = π r²           ,where r is radius of circle

So, Area of quarter circle = \dfrac{1}{4} ×  π r²          

where r = 10 cm

So, The Area of 4 quarter circle each at four sides on square = 4 × \dfrac{1}{4} ×  π r²          

Or, Area of 4 quarter circle =  π r² = 3.14 × (10 cm)²

i.e Area of 4 quarter circle = 314 cm²

Now,

Area of shaded region = Area of square - Area of 4 quarter circle

i.e A = 400 cm²  -  314 cm²

∴  A = 86 cm²

Hence,  The Area of shaded portion is 86 cm²  . Answer

(B)

From figure

A square ABCD with side length = 20 cm

∵ Area of square = side²

Or, Area of square = (20 cm) ²

Or, Area of square = 400 cm²

Again

The diameter of circle = side length of square

i.e D = 20 cm

So, radius = R = \dfrac{D}{2}   = \dfrac{20}{2}

i.e R = 10 cm

∵ Area of circle =  π R²

Or, Area of circle =  3.14 × (10 cm) ²

Or, Area of circle =  314 cm²

Now,

Area of shaded region = Area of square - Area of 4 quarter circle

A' = 400 cm² - 314 cm²

∴, A' = 86 cm²

Hence,  The Area of shaded portion is 86 cm²  . Answer

(b) Find the greatest number which divides 96 and 108 without aremainder.​

Answer»

Given,

The dividend NUMBERS are 96 and 108.

To find,

The greatest divisor which can divide both the dividends without LEAVING a remainder.

Solution,

To find the greatest divisor,we have to find the greatest common factor or GCF of 96 and 108.

By mathematical CALCULATIONS,we get that GCF of 96 and 108,is 12.

Now, 12 can divide both the 96 and 108 , without leaving any remainder. And,there are no higher number than 12 which can do the same.

Hence,the number is 12.

If m and n are the roots of quadratic equation X square - 5 x + 3 is equal to zero then find the value of M + nwhole square + A minus nwhole square ​

Answer»

<P>Let us know the RELATION between roots and coefficients first:

We consider the following quadratic EQUATION

ax^2 + BX + c = 0

If p, q be its roots, then

  • p + q = - b/a
  • pq = c/a

Now we proceed to solve the given problem:

The given equation is

x^2 - 5x + 3 = 0

The roots are m and n. Then

  • m + n = - (- 5/1) = 5
  • mn = 3/1 = 3

Therefore, (m + n)^2 + (m - n)^2

= (m + n)^2 + (m + n)^2 - 4mn

= 2 (m + n)^2 - 4mn

= 2 (5)^2 - 4 (3)

= 2 (25) - 4 (3)

= 50 - 12 = 38

∴ (m + n)^2 + (m - n)^2 = 38

Prove 2+√3 is irrational​

Answer»

Answer:

Let 2-√3 be rational no.

So,2-√3=p/q

-√3=p/q-2

Since,a and B are integers,a/b-2 is a rational NUMBER and

therefore,-√3 is a rational no.

but this CONTRADICTS the fact that it is a IRRATIONAL number.

This CONTRADICTION arises as we have assumed 2-√3 a rational number.

So,2-√3 is a irrational no.
