Long story short ,

Im not good in math and this is my first question, my best guess is D
I will investigate tommorow this problem a little bit more... <3
Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches. b.
Hope this helps have a nice day
