Calculate the area of the base of a fountain if the distance from the center of the fountain to the edge of the base is 10ft

a. 314 sq ft
b. 414 sq ft.
c. 514 sq ft
d. 614 sq ft

I believe the answer is A 3.14(10)(10) = 314 sq ft

Yep! Right again!

Yes -- pi x the radius squared

To calculate the area of the base of the fountain, we need to find the area of a circle. The formula to calculate the area of a circle is:

A = πr^2,

where A is the area, π is a constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the distance from the center of the fountain to the edge of the base is given as 10ft, which is the radius (r) of the circle. Therefore, we can substitute the value of r into the formula and calculate the area of the base.

A = 3.14 * (10ft)^2

A = 3.14 * 100ft^2

A = 314 ft^2.

Therefore, the correct answer is a. 314 sq ft.
