Chapter 11, Problem 13PT

To determine

To calculate: The area of given circle.

Answer to Problem 13PT

The area of the circle is $113.097{\text{cm}}^{\text{2}}$ .

Explanation of Solution

Given information: The radius of the circle is $6\text{cm}$

Concept Used:

The area $A$ of the circle having radius $r$ is

  $A=\pi r^2$

Calculation:

The area $A$ of the circle having radius $r$ is

  $A=\pi r^2$

In the question, the radius of the circle is $6\text{cm}$

Then the area is

  $\begin{array}{l}A=\pi \times 6^2\\ A=\frac{22}{7}\times 36\\ A=113.09{\text{cm}}^{\text{2}}\end{array}$

Conclusion:

The area of the circle is $113.097{\text{cm}}^{\text{2}}$ .
