Question

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

Answer 1

Answer:

given

Circumference of flower bed = 88m

Let the radius of flower bed = r

2×22/7×r = 88

r = 14m

Circumference of circular path = 132m

Let the radius of circular path = R

2×22/7×R = 132

R = 21m

width of circular path = R - r = 21 - 14

= 7m

Area of path = area of circular path - area of flower bed

= 22/7×21×21 - 22/7×14×14

=1386 - 616

= 770 m
