Question

find the radius of a circle whose circumference is 39.6m

Answer 1

2πr=39.6,

2×22/7 × r=39.6,

then

r=39.6 × 7/44,

r=6.3 cm

Answer 2

hey there here is your answer

given: circumference of the circle = 2πr=39.6m

so, 2×22/7×r=39.6

=> 44/7× r = 39.6

=> r = 39.6 × 7/44

=> r = 6.3

hope it helps you

thanks
