(b) 28 cm​

Answer 1

(a) 14 cm

$\tt \huge \red{ƛɳʂῳɛя : }$

We are given that

Radius of circle = 14 cm

We know that

Circumference of the circle = 2πr

= 2 × (22/7) × 14

= 2 × 22 × 2

= 88 cm

(b) 28 cm

• Answer

We are given that

Radius of circle = 28 cm

• We know that

Circumference of the circle = 2πr

= 2 × (22/7) × 28

= 2 × 22 × 4

= 176 cm

(c) 21 cm

• Answer

We are given that

Radius of circle = 21 cm

We know that

Circumference of the circle = 2πr

= 2 × (22/7) × 21

= 2 × 22 × 3

= 132 cm
