Question

1. 27 ft a= ft²

Explanation:

Step1: Find the radius

The diameter \(d = 27\) ft. The radius \(r=\frac{d}{2}\), so \(r=\frac{27}{2}=13.5\) ft.

Step2: Use the area formula for a circle

The area formula of a circle is \(A=\pi r^{2}\). Substitute \(r = 13.5\) into the formula: \(A=\pi\times(13.5)^{2}\).
Calculate \((13.5)^{2}=13.5\times13.5 = 182.25\). So \(A = 182.25\pi\approx182.25\times3.14=572.265\) \(ft^{2}\)

Answer:

\(572.265\)
