Chapter SH, Problem 11.8.1EP

To determine

Calculate the area of circle having radius of 8.2 ft

Answer to Problem 11.8.1EP

Area of circle is $211.24f{t}^2$

Explanation of Solution

Given:

Radius of circle = 8.2 ft

Calculations:

Here, we have to calculate the area of a circle.

We know that, area of a circle is given as, $\pi r^2$

Now putting values in the formula, we get area of a circle,

  $\begin{array}{l}Areaofcircle=\pi r^{2`}\\ =\pi \times {8.2}^2\\ =211.24f{t}^2\\ \end{array}$

Conclusion:

Therefore, we are able to find the circumference of a circle.
