Question

A circular park of radius 15 m has a path of 10 m width around its outer side. Find the area of the road.

Answer 1

Find the area of the park:

Area = πr²

Area = π(15)² = 225π m²

Find the radius of the park and road:

Radius = 15 + 10 = 25 m

Find the area of the park and road:

Area = πr²

Area = π(25)² = 625π m²

Find the area of the road:

Area =  625π - 225π = 400π = 1257.14 m²

Answer: The area of the road is 1257.14 m²
