Answer:
A = .785 inches ^2
Step-by-step explanation:
C = pi *d
We know the diameter = 2*r
C = pi*2*r
Substituting pi = 3.14 we can solve for r
3.14 = 2*pi*r
3.14 = 2*3.14 *r
Divide by 3.14 on each side
3.14/3.14 = 2*3.14 *r/3.14
1 = 2r
Divide by 2
1/2 =2r/2
1/2 =r
Now we can find the area
A = pi *r^2
A = 3.14 *(1/2)^2
A= 3.14 *1/4
A = .785 inches ^2

Answer: 288
Explanation:
Split the shape up into a rectangle and triangle (shown in picture).
Find the lengths of the triangle:
Height:
28 - 12 = 16
Base:
16 - 4 = 12
Find the area of the rectangle:
12 x 16 = 192
Find are of the triangle:
(12 x 16) ÷ 2 = 96
Add them together:
96 + 192 = 288
