Question

Calculate the circumference of a circle with a radius of 8 inches.

Answer 1

To calculate the circumference of a circle, you can use the formula:

`\displaystyle C=2\pi r`

Where
`\displaystyle C` represents the circumference and
`\displaystyle r` represents the radius of the circle.

Given that the radius
`\displaystyle r` is 8 inches, we can substitute this value into the formula:

`\displaystyle C=2\pi (8)`

Simplifying the expression:

`\displaystyle C=16\pi`

Thus, the circumference of a circle with a radius of 8 inches is
`\displaystyle 16\pi` inches.

Note:
`\displaystyle \pi` represents the mathematical constant pi, which is approximately equal to 3.14159.
