Question

3) The circumference of the circular ground is 132 m. lawn is made inside the ground
to play cricket, leaving a space of uniform width of 7 m. along the circumference
Find the area of the lawn.​

Answer 1

Circumference of circle = 2πr

132 = 2 × 22/7 × r

132 = 44/7 × r

132 × 7/44 = r

3×7 = r

21 = r

The lawn is made inside the ground,

r - 7 = 21-7 = 14

Circumference of circle,

Circumference of lawn = πr^2

=22/7×14×14

=22×2×14

= 616 sq.m.
