Question

Find the circumference and the area of a circle with 6m.

write your answer in terms of π, and be sure to include the correct units in your answer

​

Answer 1

C =
`12\pi m`

A =
`36\pi m^2`

Explanation:

I'm going to assume that the radius is 6m. The circumference of a circle is
`C = 2r\pi`. So we can plug in 6 for r and we get the circumference is
`12\pi m`.

For area, the equation is
`A = \pi r^(2)`. So we can again plug in 6 for r and we get that the area is
`36\pi m^2`.

If 6m is the diameter, then the circumference is
`6\pi m` and the area is
`9\pi m^2`.
