Question

The radius of a circle is represented by the expression x+3. Express the circumferend terms of x​

Answer 1

The circumference of circle with radius x+3 is:
`2\pi x+6\pi`

Explanation:

Given that

Radius = r =x+3

The circumference of a circle is the distance around boundary of the circle.

The circumference of circle is given by the formula.

`C = 2\pi r`

Putting the value of r, we get

`C = 2\pi (x+3)\\C = 2\pi x+6\pi`

Hence,

The circumference of circle with radius x+3 is:
`2\pi x+6\pi`
