Answer 1

do you know the formula for finding the volume of a cylinder?

Answer 2

volume = pi x r2

Answer 3

one more variable missing.
it is volume=pi x r2 x h

Answer 4

That's a good way to remember volume of a cylinder. you'll need to know that in the future :) \[V = \pi r^2 h\]

Answer 5

\[r=\frac{D}{2} = \frac{10}{2} = 5 \] (missing units)\[V = (3.14)(5)^2(12)\]

Answer 6

So you'd have V = ________ units^3

Answer 7

942

Answer 8

ok thnx!
