Answer:
- Area of the circle is 56.25π square feet. 
Step-by-step explanation:
<u>Given that</u>:
- The circumference of a circle is 15π ft.
<u>To Find</u>:
- What is the area, in square feet? 
<u>We know that</u>:
- Circumference of a circle = 2πR
- Area of a circle = πR²
Where, 
<u>Finding the radius of the circle</u>:
Circumference of a circle = 15π
 ⟶ 2πR = 15π
 ⟶ 2πR = 2π × 7.5
Cancelling 2π.
 ⟶ R = 7.5
∴ Radius of the circle = 7.5 ft. 
<u>Finding the area of the circle</u>:
 ⟶ Area = πR²
 ⟶ Area = π(7.5)²
 ⟶ Area = π × 7.5 × 7.5
 ⟶ Area = π × 56.25
 ⟶ Area = 56.25π
∴ Area of the circle = 56.25π ft.²

Hi there! Your answer would be:
D, If it is an octagon, then it does not have exactly five sides.
I also know because I took this exam and it was correct.
Hope that helps!
