A cylindrical water tower has a radius of 3-5 yards. The top of the water tower is a circle. What is the area of the circular water tower top? (Recall that the area of a circle is, wherer is the radius.)

8-15

A.

(69-1615) square yards

B.

(69 - 8/5)

square yards

C. 697 square yards

D.

69 + 16/5

square yards

Replace the radius into the equation and compute the area

Step-by-step explanation:

The area of a circle is computed as follows:

area of a circle = π*r²

where r is the radius of the circle.

I cannot understand which radius has the circle. In the case that r = 3 yards, the area is:

area of a circle = π * (3) ² = 28.3 yd²

And in the case that r = 5 yards, the area is:

area of a circle = π*5² = 78.5 yd²
