Question 844805
A right circular cylinder with a diameter D = 21 cm and a height h = 34 cm has a hole with a diameter d = 8 cm drilled through its center.
 The approximate volume of the cylinder with the hole drilled through the center would be ________ cu cm.
:
radius of the cylinder: 21/2 = 10.5 cm
radius of the hole: 8/2 = 4 cm
:
The hole volume is also a cylinder, subtract the vol of the hole from the vol of the cylinder
V = {{{pi*10.5^2*34}}} - {{{pi*4^2*34}}}
