Answer 2

Here's the answer

Given :

Radius => 3.5 cm

To find :

Circumference => ?

Solution :

We know that,

$\sf{ \underline{Circumference \: of \: circle =2 π r}}$

$\sf{ = 2 \times \frac{22}{7} \times 3.5}$

$\sf { = 2 \times 22 \times 0.5}$

$\sf{ = 44 \times 0.5}$

$\sf{ = 22 \: cm}$

Hence,

It's circumference will be 22 cm
