The Inland Propane Gas Tank Company wants to make tanks with this shape, and to offer models in different sizes. The cylindrical portion of each of the different tanks will be
One of the tank models has a radius of
meter. What is its volume?
for in the sphere and cylinder equations.
Now add the values together.
If the radius is doubled, will the volume double? Explain. Then calculate the volume of the larger tank with
Remember that the radius is being cubed.
The radius will not double because of the
Now, see part (a).
The tank will be
Write an equation that will let the Inland Propane Gas Tank Company determine the volume of a tank with any size radius.
Remember that the total is the combination of a sphere and a cylinder.
