Question

Find the area of a circle whose diameter is 27 inches. (Use pie = 3.1416.)

Answer 1

The area of circle is 572.5566 in^2

Explanation:

We have that the area of the circle is the following

`A=\pi\cdot r^2`

Where r is the radius, and the radius corresponds to half the value of the diameter, replacing and calculating the area we have left:

`\begin{gathered} d=(27)/(2)=13.5 \\ A=3.1416\cdot13.5^2 \\ A=572.5566 \end{gathered}`
