Which equation could be used to find the circumference, in inches, of a garbage can if the radius of its circular basis is 10 inches?

Answer:
it should be D
Step-by-step explanation:
the formula is πr^2, and d is π*10^2
Answer: A
The circumference formula for a circle is 2 x pi x r. So if the radius is 10 then 2 x 10 = 20. Then 20 x pi.
