Question 1013428
1.An Ice Cream cone has a base diameter of 8 cm and a height of 13 cm. What is its volume?
{{{Vol = pi*r^2h/3}}}
r = 4
=======================
2.A cylinder and a cone have the same diameter and the same height. The volume of the cone is 36.5 cm. What is the volume of the cylinder?
3*36.5 = 109.5 cc  ---- not cm, cubic centimeters.
======================
3.A cone-shaped container has a base diameter of 18 cm and a height of 30 cm. How much volume of water will fill it to the brim?
Same as #1.
======================
4.A 20-cm high pyramid has a square base whose side measures 14 cm. What is the volume of the pyramid?
Vol = base area*h/3
=======================
5.How much more water does a cylindrical-shaped cup contain than a cone-shaped cup if both have the same diameter and height?
For a cylinder:  {{{Vol = pi*r^2*h}}}
===========================
6.The Formula for the volume of a sphere is V= 3/4 π r3. Find the volume of a balloon whose diameter is 18 cm.
It's {{{4pi*r^3/3}}} not 3/4
