Question

Find the exact circumference of a circle with a radius of 6 m.

Answer 1

`12\pi` inches.

Explanation:

We are given that,

The radius of the circle = 6 inches

Since, the circumference of a circle =
`2\pi r`, where r = radius.

Substituting r = 2 in the formula, we get,

Circumference of a circle =
`2\pi` ×
`6=12\pi` inches

Hence, the circumference of the circle is
`12\pi` inches.

So,
`12\pi` is correct.
