Answer:
98 pi inches ^2
Step-by-step explanation:
We know that the diameter is 28 inches
The radius is 1/2 diameter
r = 14 inches
Area of a circle is pi * r^2
A = pi r^2
= pi (14)^2
= 196 pi
A semi circle is 1/2 of a circle,so we take 1/2 the area
A semi circle = 1/2 A circle
= 1/2 (196 pi)
= 98 pi inches ^2
