Solution!!

There are 3 cases given in which the diameters of different circles is given. We have to find the circumference of those circles.

(i) Diameter = 17.5 cm

Radius = 17.5 ÷ 2

Radius = 8.75 cm

Circumference = 2πr

Circumference = 2 × (22/7) × 8.75

Circumference = 2 × 22 × 1.25

Circumference = 55 cm

(ii) Diameter = 5.6 cm

Radius = 5.6 ÷ 2

Radius = 2.8 cm

Circumference = 2πr

Circumference = 2 × (22/7) × 2.8

Circumference = 123.2/7

Circumference = 17.6 cm

(iii) Diameter = 4.9 cm

Radius = 4.9 ÷ 2

Radius = 2.45 cm

Circumference = 2πr

Circumference = 2 × (22/7) × 2.45

Circumference = 107.8/7

Circumference = 15.4 cm
