Question

A path of width 4 meters run around a circular park whose radius is 12 m.find the area of the path.

Answer 1

Answer:

352 m

Step-by-step explanation:

Answer 2

Width of the Path: 4m

Radius of Ground including path: 12m

Radius of Ground excluding path: 8m

Area of path = Radius of Ground including path - Radius of Ground excluding path

Area of path = $\pi 12^{2} - \pi 8^{2}$ = $\pi (12^{2} - 8^{2}) = \pi ((12+8)(12-8)) = \pi$(20×4)

= 3.14 × 80 = 251.2 meter-square
