+23PTS! PDF Volume question -_- find diameter from the cylinder. I got 9 answer is 6 how???

Serga [27]

Answer: See below

Explanation:

For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.

$V=\pi r^2h$ (Volume of cylinder)

$72\pi =\pi r^2h$ (The π cancel out)

$72 =r^2(8)$ (Plug in h=8)

$9=r^2$ (Divide 8)

$r=3$ (Square root of 9 is 3)

Now that we have our radius, we can find our diameter.

$d=2r$ (Equation for diameter)

$d=2(3)\\$ (Plug in r=3)

$d=6yards$ (Multiply)
