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.
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)
To write an expression for the volume of the vase using the given formula V = (4/3)πr^3, we need to substitute the radius value into the formula.
The radius of your vase is given as 21/2 inches.
So, to find the volume expression, we replace "r" with the given radius in the formula:
V = (4/3) * π * (21/2)^3
Now, let's simplify the expression:
V = (4/3) * π * (441/8)
V = (4 * 3.14 * 441) / (3 * 8)
V = 1847.52 / 24
Therefore, the expression for the volume of your vase is V = 76.98 cubic inches.
