Answer:
Step-by-step explanation:
the equation for a cone is V= pir^2h
we plug in our units to get 36pi = pi(r^2)(12)
we divide 12 from each side to get 3pi=pi(r^2)
divide pi on each side to get 3 = r^2
square each side to get the radius = sqrt 3
find the diameter by multiplying sqrt3 times 2 = 3
The circumference is 3pi.
