What is the exact circumference of a circle with a radius of 3 ft

Answer: 6r

Answer: 18.85ft

Step-by-step explanation:

The formula for the circumference of a circle is C = 2 x (Pi) x r, where r is equal to radius.

Pi is a constant number equal to 3.14, but if your calculator has a Pi button you should use that rather than typing in the numbers as it has a higher accuracy.

In this case we would do;

C = 2 x 3.14 x 3

Which gives us C = 18.85ft
