Answer 1

Given:- Radius of inner circle

Radius of outer path

To Find:- Area of the path

Formula used:- (Area of outer circle - Area of inner circle)

Area of circle= 2 ×pie× R

2× 22/7 × (11+3=14)

2×22/7×14 =

88 sq. cm.

Area of inner circle = 2×22/7×11=

484/7= 69.14 sq. cm.

Area of the path = 88 sq. cm. - 69.14 sq. cm. = 18.86 sq. CM.

Ans:- 18.86 sq. cm
