Question

if the circumferenceof a circle is 176 cm, find it's radius​

Answer 1

Given :-

Circumference of a Circle = 176 cm

To Find :-

Radius of the Circle

For that, we will use the formula of Circumference.

There is no mention of the value of π so we will take it's value 22 / 7.

C = 2πr cm

176 = 2 × 22 / 7 × r cm

176 = 6.28 × r cm

r = 176 / 6.28 cm

r = 28.02 cm

Hence, radius of the circle will be 28.02 cm.

Answer 2

Circumference = 176 cm

2πr = 176 cm

3.14 × r = 176 ÷ 2

3.14 × r = 88 cm

r = 88 ÷ 3.14

radius = 28.02 cm

Therefore radius of circle is 28.02 cm
