Given :- we have

two cirlcle whose radius are 3.5 cm and 7cm.

Find :- their circumference.

solution :-

In 1 st circle

radius = 3.5cm

circumference of circle = π × 2 r

= 22/7 × 2 × 3.5cm

= 22 cm

similarly, In 2nd circle

radius of circle = 7cm

circumference of circle = π × 2 r

= 22/7 × 2 × 7cm

= 44 cm
