Chapter 11.7, Problem 23PPS

To determine

To find: Circumference of circle.

Answer to Problem 23PPS

The circumference of a circle is $2\pi ,4\pi ,6\pi ,8\pi ,10\pi$.

Explanation of Solution

Given information:

Radius of circle is mentioned in the problem.

Formula used:

Circumference of circle is $2\pi r$ where $r$ is radius of circle.

Calculation:

Consider the statementCircumference of circle.

And mentioned radius is $r=1,r=2,r=3,r=4,r=5$ where r is radius.

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

Therefore the circumference correspond to $r=1$ then C is $2\pi *1=2\pi$ .

Again circumference correspond to $r=2$ then C is $2\pi *2=4\pi$ .

Again circumference correspond to $r=3$ then C is $2\pi *3=6\pi$ .

Again circumference correspond to $r=4$ then C is $2\pi *4=8\pi$ .

Again circumference correspond to $r=5$ then C is $2\pi *5=10\pi$ .Where C is circumference of circle.

Therefore the circumference of circle is mentioned above .
