Question

3. The radius of a circle is 7cm. Find the circumference of the circle. Use 22 for pi. . .​

Answer 1

44cm

Explanation:

The formula to find the circumference of a circle is :

C = 2 π r

Here,

r ⇒ radius ⇒ 7cm

π ⇒ 22/7

Let us find now.

C = 2 π r

= 2 ×
`(22)/(7)` × 7

= 14 ×
`(22)/(7)`

=
`(308)/(7)`

= 44 cm
