The radius of a circular disc is 5.8 inches. find the circumference. use 3.14 for n

A) 18.121 in

B) 36.424 in

C) 42.34 in

D) 54.63 in

It is B.

The formula for the circumference of the circle is Pi x diameter. Since you only have the radius, you must times the radius by two to get the whole diameter. The diameter is 11.6. Now 11.6 times Pi equals 36.424

I think it is A. Although you might have mixed up the numbers because I got 18.212

Work:

5.8 x 3.14
