Question

How to find the radius when circumference is given?

Answer 1

Answer:

divide circumference by 2π

Step-by-step explanation:

let radius be r

circumference = 2πr

therefore circumference/2π =radius

Answer 2

Answer:

You can find the radius when circumference is given by just putting the formula of circumference that is 2*pi*radius an finding the value of radius

Step-by-step explanation:

for example,

circumference is given as 154 cm

then,

2*pi*r = 154 cm

2*22/7*r = 154 cm

r = 154 cm*1/2*7/22                     (transposing 2 and 22/7 to right side)

r = 77cm*7/22

r = 24.5 cm
