Answer:
21.07 yd^2
Step-by-step explanation:
The width of the rectangle is also the radius of the semicircle. The length of the rectangle is 2 radii, or 14 yd.
The area of the shaded region is the same as the area of the semicircle subtracted from the area of the rectangle.
area of shaded region = area of rectangle - area of semicircle
A = LW - (1/2)(pi)r^2
A = 14 yd * 7 yd - (1/2)(3.14)(7 yd)^2
A = 98 yd^2 - (1.57)(49 yd^2)
A = 98 yd^2 - 76.93 yd^2
A = 21.07 yd^2

Answer:
x=8a
Step-by-step explanation:
3/a x-4=20
We need to solve for x
Add 4 to each side
3/a x-4+4=20+4
3/a x = 24
Multiply each side by a/3 so we can get x alone
a/3 *3/a x = 24 * a/3
x = 8a
