Question

How do i find the circumference of a circle when the given radius is 3 1\2 cm, answers in terms of π

​

Answer 1

Circumference of circle is 9.42cm.

Explanation:

Here we have given that A circle with having radius 3 and 1 / 2 cm. And We need to find circumference of circle.

Formula using

Circumference of circle = π × 2 × radius

substitute the value

Circumference of circle = π × 2 × 3 and 1/2 cm.

cancle the 2

Circumference of circle = π × 3 cm

Using π = 22 / 7

`\small \sf \ Circumference \: of \: \: circle = ( 22)/(7 )×3 cm \\`

`\small \sf \ Circumference \: of \:circle = 9.42 cm`

Hence, Circumference of circle is 9.42cm.
