If r = 4 units and x = 11 units, then what is the volume of the cylinder shown above?
A. 120 cubic units
B. 44 cubic units
C. 176 cubic units
D. 704 cubic units
@IGREEN i think its B

Answer 1

No, you don't divide 2 to the radius..we already have it..you only divide by 2 if you're given the diameter.

Answer 2

So we have:

\(\sf V = \pi r^2h\)

\(\sf V = \pi(4^2)(11)\)

Simplify 4^2 * 11

Answer 3

so its A @igreen

Answer 4

Wait..no..it's not..check again.

Answer 5

\(\sf 4^2 \times 11 \rightarrow 4 \times 4 \times 11\rightarrow~ \! ?\)

Answer 6

its C

Answer 7

Yep, you got it. 176.
