Question

A circular path runs around a circular flower bed.If the circumference of the flower bed and path are 88m and 132cm respectively. Find the width of the path. Also, find the area of path.​

Answer 1

Circumference of the flower bed = 2πr

88 cm = 2 × 22/7 × r

88 × 7 /2/22 cm. = r

14 cm. = r

Circumference of the path = 2πr

132 cm. = 2 × 22/7 × r

132 × 7/2/22 cm. = r

21 cm. = r

Area of the path = πr sq.

= 22/7 × 21 × 21 cm sq.

= 1387 cm sq.
