Question

If a circle has a circumference of 60π, which equation shows the correct value for the radius, r?

1) r=2π
2) r=60π
3) r is equal to 60 over pi
4) r=60π2π

Answer 1

The correct equation for the value of the radius in a circle with a circumference of 60π is r = 30.

Step-by-step explanation:

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.

In this case, the circumference is given as 60π, so we can set up the equation 60π = 2πr.

To find the value of r, we can divide both sides of the equation by 2π, giving us r = 30.

Therefore, the correct equation for the value of r is r = 30.
