Question 1048685
<font face="Times New Roman" size="+2">


The volume of a cylinder is the area of the base times the height, so *[tex \Large \pi r^2h].  The volume of a sphere is *[tex \Large \frac{4}{3}\pi r^3], and a hemisphere is half of a sphere so, *[tex \Large \frac{2}{3}\pi r^3].


The volume of a cylinder and a hemisphere together is the sum of the two volumes, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  V\ =\ \pi r^2h\ +\ \frac{2}{3}\pi r^3]


You can do a little algebra to simplify the arithmetic:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  V\ =\ \pi r^2\left(h\ +\ \frac{2}{3}r\right)]


Plug in the given values and do the arithmetic.  Remember you are given the diameter which is two times the radius.

My calculator said it, I believe it, that settles it
