Question

If the circumference of a circle is 5π what is the radius? PLEASEEEEEEEE HELP

Answer 1

2.5 is r bc circumference is 2r and for it to be 5 it would have to be 2 times something and half of 5 is 2.5

Answer 2

Circumference is the distance around the edge of a circle, radius is the distance from the center of a circle to the edge of the circle.

To find circumference you use the formula
C = 2(r)(pi)

Where
C = circumference
r = radius
pi =

The 2 is there because of you multiply the radius by 2 you will get the diameter, the distance across the entire circle that goes through the center of the circle.


In this problem you have the value of C, therefore

5 = 2r

Now you can solve.

5 = 2r
5 = 2r
5/2 = r = radius
