love history [14]

Answer:

0.9675sq.cm

Step-by-step explanation:

Find a related diagram attached

Area of the shaded region = Area of rectangle - area of semicircle

Area of rectangle = 3cm * 1.5cm

Area of rectangle = 4.5sq.cm

Given

diameter of the semicircle = 3cm

area = πd²/8

Area of the semicircle = 3.14(3)²/8

Area of the semicircle = 3.5325sq.cm

Area of the shaded region = 4.5 - 3.5325

Area of the shaded region = 0.9675sq.cm

A≈21.46
First you find the area of the square

A=a^2 which is
=10^2
A=100

Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54

Now you subtract the 78.54 from 100 to get 21.46
