Question

find the area of shaded portion of the following figures.(π=22/7)​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

A1 = Area of the ( outer ) C1= πr1^2 and r1= 14 cm

=22/7 x 14 x 14= 616

A2 = Area of the ( inner ) C2= πr2^2 and r2= 7 cm

=22/7 x 7x7= 154

Shaded region = A1 -A2 = 462 cm2
