Question

A circular running track has a inner radius 126m and an outer radius 140m. Find the area of the track​

Answer 1

Step-by-step explanation:

For outer Track -

Radius = 140 m

Area = π r²

= 22/7×19600

= 61,600 m²

For the inner Track -

Radius = 126 m

Area = π r²

= 22/7× 15,876

= 49,896 m²

now area of track

= area of outer track - area of inner Track

= 61,600 m² - 49,896 m²

= 11,704 m²
