Question

find the radius of a circle whose circumference is 44 m

Answer 1

circumference of a circle is 2 π r

So circumference is given in the question ,

2π r=44

π*r=44/2

π *r= 22

22/7 *r= 22

r= 22*7/22 ( 22 will cancel our )

r = 7

Therefore the radius of the circle is 7 m

Answer 2

cirrcumference of circle =2πr
2πr = 44 m
πr = 44/2
πr = 22 m
22/7*r = 22 m
7/22*22
r = 7 m
