Answer:
$80
Step-by-step explanation:
15(x+20) = 1500
15x + 300 = 1500

Divide each side by 15
x = 80
The formula for finding the area of a circle is
a = pi × radius^2
Since the diameter is 14 inches, the radius is 7 inches, so to solve...
a = pi × 7^2
a = 3.14 × 49
a = 153.86
Rounded to the nearest tenth...
153.9 inches^2
