Chapter 11, Problem 14PT

To determine

To find: The area of the circle.

Answer to Problem 14PT

The area of the circle is $38723.14m^2$ .

Explanation of Solution

Given Information: Given diameter is $222m$ .

Calculation :Given diameter is $222m$ .

Radius $=\frac{222}{2}=111\mathrm{m}$ .

Area of circle:

  $\begin{array}{l}=\pi r^2\\ =\frac{22}{7}\times 111\times 111\\ =38723.14m^2\end{array}$

Thus, the area of the circle is $38723.14m^2$ .
