What is the exact area of a semicircle with diameter of 28 inches?

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

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
