If a tank's radius is 49.8 ft, what is the area of the tank's bottom?

Explanation:
Area of a circle is πr^2. With a radius of 49.8 ft, r^2 = 49.8 × 49.8 = 2,480.04. Multiply by π: A ≈ 2,480.04 × 3.14159 ≈ 7,791 ft^2. Rounding to the nearest ten gives about 7,790 ft^2, which matches the option closest to this value.
