Answer

Step-by-step explanation

Given:

Diameter of the circle = 12 ft

π = 22/7

To determine the area of a circle with a given diameter, we use the formula:


A=(1)/(4)\pi d^2

where:

A=Area

d=diameter

We plug in what we know:


\begin{gathered} A=(1)/(4)\pi d^(2) \\ =(1)/(4)((22)/(7))(12)^2 \\ Calculate \\ A=113.1ft^2 \end{gathered}
