Answer 2

Here we have to find the circumference of circles with given radius :-

• a)14cm
• b)28mm
• c)21cm

We know that :-

• Circumference = 2πr
• Value of π = 22/7

A) 14cm

→ 2 * 22/7 * 14

→ 44 * 4

→ 88cm.

B) 28mm

→ 2 * 22/7 * 28

→ 44 * 4

→ 176mm.

C) 21cm

→ 2 * 22/7 * 21

→ 44 * 3

→ 132cm.

Answer :-

• a) 88cm

• b) 176mm

• c) 132cm
