Question

area of a circle is equal to the area of a rectangle with side 112m and 88 metre respectively find the circumference of the circle

Answer 1

first, area of rectangle =length*breadth

here, area of rectangle=112*88

area of rectangle=9856metre(square)

area of rectangle = area of circle

9856=area of circle

9856=22*r*r/7

9856*7/22=r*r

3136=r^2

under root 3136=r

56=radius of the circel

circumference of the circle=2*22*56/7

circumference =44*8

circumference of the circle=352metre



i hope this much will help you

Answer 2

Area of Circle = Area of Rectangle

Rectangle
l = 112m
b = 88 m

Area = l*b
        = 112*88
        = 9856m²

Area of Circle = 9856m²
Radius = ?
Area = πr²
9856 = 22/7 * r²
r² = 9856*7/22
r² = 3136
⇒ r = √3136
r = 56

Circumference of circle = 2πr

= 2 * 22/7 * 56
= 352m
