two assumptions:
V =(4/3)π r^3
radius is 2 1/2 inches or 2.5 inches
so V = (4/3)π(2.5)^3 inches^3 = ....
(I get appr 65.4)
Glass Vase You are taking a glass-blowing class and have created a vase in the shape of a sphere. The vase will have a hole in the top so you can put flowers in it and it will sit on a stand. The radius of your vase is 21/2 inches. Use the formula V=4/3:r^3 to write an expression for the volume of your vase.
