Question

A cylinder has a base diameter of 4in and a height of 7in. What is its volume in cubic in, to the nearest tenths place?

Answer 1

\[V= \pi*r^2*h\]
\[2r=d\]
h= height
d = diameter
r = radius
V= volume

Answer 2

No, that wouldn't be the right answer. Using the equation, \[V = \Pi \times r^2 \times height\] and
\[d = 2r\] You would find that the radius is 2 and implementing that into the equation for Volume, you would get \[V = \pi \times 2^2 \times7\] and once solved, it would be \[28\pi\] or 88 cubic inches.
