If the Circumference is 6 ft. What is the radius?

To find the radius of a circle using the given
circumference we use the formula for finding
Circumference.

C=2pi(r)

Using
3.14 for pi and 6 for the Circumference, we solve for r
(radius).

6=2(3.14)r     (multiply 2 times
pi)

6=6.28r         (divide each side
of the equal sign by 6.28)

r≈.955          
(the result is that r is approximately
.955)

Rounding to the nearest hundredths place
the radius is about .96 ft.
