Question

(select the answer closest to yours.) 314 ft² 5,024 ft² 2,826 ft² 1,256 ft² 20 ft 1.3.6.kc11

Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius.

Step2: Identify radius value

The radius $r = 20$ ft as given in the problem.

Step3: Calculate area

Substitute $r = 20$ into the formula: $A=\pi\times(20)^{2}=\pi\times400$. Taking $\pi\approx 3.14$, we have $A\approx3.14\times400 = 1256$ ft².

Answer:

1,256 ft²
