Answer:
8 inches
Explanation:
The formula for a cone's volume is: V = (pir^2h)/3
We already have the V, or volume and the height (h).
So: 100.48 = [pi(6)r^2]/3
Simplify: 100.48 = [(18.84955592154)r^2]/3 (=) 301.44 = (18.84955592154)r^2 (=) 16 = r^2 (=) 4 = r, and since the diameter is 2 times the radius, the diameter is 8 inches.
