Question

Find the area of the shaded region in which the radius of semicircle is 9/2 and the diameter of circle is 9/2

Answer 1

Answer:

(22/7)* (81/16)

Step-by-step explanation:

area of semi cicle= [(22/7)*( 9/2)^ 2]/2

area of circle=(22/7)*(9/4)^2

area of the shaded portion = (22/7)* ([ 81/8]-[81/16])=(22/7)*[ 81/16]=891/56=15.91
