Chapter 11.8, Problem 31PPS

To determine

To find: Area of circle.

Answer to Problem 31PPS

The area of a circle is $9\pi ,36\pi ,144\pi ,576\pi ,2304\pi$.

Explanation of Solution

Given information:

The radius of circle is mentioned in the problem.

Formula used:

Area of circle is $\pi r^2$ where $r$ is radius of circle.

Calculation:

Consider the statement area of circle.

And mentioned radius is $r=3,r=6,r=12,r=24,r=48$ where r is radius.

Recall that area of circle is $\pi r^2$ where $r$ is radius of circle.

Therefore the area correspond to $r=3$ then area is $\pi *3^2=9\pi$ .

Again areacorrespond to $r=6$ then area is $\pi *6^2=36\pi$ .

Again area correspond to $r=12$ then area is $\pi *{12}^2=144\pi$ .

Again area correspond to $r=24$ then area is $\pi *{24}^2=576\pi$ .

Again area correspond to $r=48$ then area is $\pi *{48}^2=2304\pi$ .

Therefore the area of circle is mentioned above.
