Question

find the radius of circle whose circumference is 88m

Answer 1

2πr=88
22r/7=44
r=44×7/22
r=14m.The radius of the circle is 14m.

Answer 2

Q. Find the radius of circle whose circumference is 88 m.

Solution :

Given :-
Circumference of circle = 88 m

Let the radius be 'r'

Now,
Circumference of circle = 2πr ( in which 'r' is the 'radius' )

=> 88 = 2 × 22/7 × r

=> 88 = 44/7 × r

=> 88 × 7/44 = r

=> 14 = r

Hence, the radius of the circle = 14 m.
