Question

the area of the circle is equal to area of the rectangle with sides 112 and 88 metre respectively find the circumference of the circle​

Answer 1

Step-by-step explanation:

Area of circle=area of rectangle

hence , area of rectangle = l×b

= 112×88 sq. m

= 9856 sq. m

area of circle= 22/7 × r×r

9856=22/7 ×r×r

9856×7/22= r × r

3136= r×r

56=r

circumfrence of the circle = 2×22/7×r

=2×22/7 × 56

= 352m

hence circumfrence of the circle is 352m

Answer 2

Answer:

area of rectangle= l*b

=112*88

= 9856 m²

As given in the question that,

• area of rectangle is equal to area of circle.

area of circle is = πr²

9856=22/7 * r²

r²= 9856 *7/22

r²=3136

r=√3136

r=56 m

so circumference of circle =2πr

=2*22/7*56

= 352m answer=352 m
