A stack of 39 pennies is exactly as tall as a stack of 31 nickels. Do the two stacks have the same volume? Explain.
Choose the correct answer below.
A. No. The two stacks have the same height, but there are more pennies than
nickels in the penny stack.
B. No. The two stacks have the same height, but the area of the cross section
of the penny stack is smaller
than the area of a cross section of the nickel
stack.
C. Yes. Using the formula for the volume of a cylinder, it can be seen that the
two stacks will have the same
volume.
