Answer:
Formula for volume of cone;
V = π[tex]r^{2}[/tex] * h/3
(I have done both 2&3 on your past question)
5.
Your radius is given already.
V = π[tex]r^{2}[/tex] * h/3
V = 3.14(9^2) * 15/3
V = 3.14(81) * 5
V = 254.34 * 5
V = 1271.7
6.
You do not have a radius so,
Half of the diameter is the radius (diameter/2 = radius);
4/2 = 2, is the radius.
V = π[tex]r^{2}[/tex] * h/3
V = 3.14(2^2) * 6
V = 3.14(4) * 6
V = 12.56 * 6
V = 75.36
