The equation for the area of a circle is,

a = \pi \times {r}^{2}

But first we need to find the radius. Simply divide the diameter by 2 to get the radius.

5 ÷ 2 = 2.5

So our radius in this case is 2.5 feet.

Substitute the number,

a = \pi \times {2.5}^{2}

Solve for the square,

a = \pi \times 6.25

A ≈ 19.63 ft^2
