A tire was found in a junkyard. The radius of the tire was 15 cm. What is the circumference of the tire?

Respuesta :

Answer:

Don't know how you have to round it, but the answer would be 94.2478

Explanation:

The formula for the circumference of a circle is c = pi * d. Filling that in, pi times the diameter (which is 30, since the radius is 15), gives us a rough answer of 94.2478.

Hope this helped!

Formula for circumference is 2(pi)r. Since the radius is 15 you substitute r for 15. If you leave it in terms of pi the circumference will be 30pi. If you combine them you will end with 94.2
X= 30 pi or 94.2
