Question

Find the diameter of the circle with an area of 14π squared inches. Round to the nearest hundredth. This is geometry(:

Answer 1

Given:

The area of the circle is,

$A=14\pi in^2$

To find:

The diameter of the circle.

Explanation:

The formula of the area of the circle is,

$A=\pi r^2$

On substitution we get,

$\begin{gathered} 4\pi=\pi r^2 \\ r^2=4 \\ r=2 \end{gathered}$

Then the diameter is,

$\begin{gathered} d=2r \\ d=2(2) \\ d=4in \end{gathered}$

Final answer:

The diameter of the circle is 4 inches.
