Question

Diameter of the circular garden is
42 m. There is a 3.5 m wide road
around the garden. Find the area of the road.​

Answer 1

Step-by-step explanation:

Given

d=42m

r=42/2

=21m

Area of circular garden=pi*r^2

=22/7*21*21

=22*63

=1386cm square

Radius of garden along with the road=21+3.5

=24.5

Area=22/7*24.5*24.5

=1886.5cm square

Area of road=1886.5-1386

=500.5cm square
