Answer:
construct AC
using Pythagoras theorem
AC2 = 4 square + 3 square
THEREFORE AC = 5cm = diameter
therefore radius = 5/2 = 2.5cm
area of circle= πr2
=22/7 * 2.5*2.5 = 19.625 cm2
area of rectangle=3*4=12cm2
therefore area of shaded region= 19.625-12
= 7.625 cm2
area of shaded region =area of circle-area of rectangle
in rectangle AC=(16+9)^(1/2)
AC=5
》radius of circle =5/2
area of circle = π×5/2×5/2
=25π/4
area of rectangle = 4×3
= 12
area of shaded region = (25π/4)-12
=(25π-48)/4
=7.63495
hope this helps you
