Question

Find the radius of a circle whose circumference is 28cm. Take π = 22/7

Answer 1

Answer:

Circumference=2*π*r

2*pi*r=28

Find r that is radius from this

Answer 2

Step-by-step explanation:

circumference=2πr

circumference of the given circle = 28cm

we have to find r=?

comparing both condition s

28= 2πr

28=2(22/7)r

14*7/22=r

r=7*7/11

r=49/11
