Question

If the circumference of a circle is equal to perimeter of a square, then find the

area of square in term of pi and radius r​

Answer 1

Answer:

Hope it will help you......

Step-by-step explanation:

Let perimeter of square =4s

Let perimeter of circle =2πr

we have 4s=2πr since the perimeters of both the square and the circle are equal

This makes s= 2πr/4

area of square equals = s (square) =( 2πr/4)

(square)

= 4π (square) r (square) / 16

area of circle equals = πr (square)

ratio of area of circle to area of square equals =

16πr (square) / 4π (square) r (square) =

4 / π = 7 * 4 / 22 = 14 / 11 ...
