Question

Help! I give medals:) Pic below
find the height and surface area of the right circular cylinder with the height equal to the diameter. Show work

Answer 1

Height=2r
Volume-128pic

Answer 2

Surface area of a circle is
\[r ^{2} \pi \]

Volume is surface area of a circle multiplied by height.
So, 128 = 2r * r (squared)*P

Answer 3

how do I solve for r?

Answer 4

\[r ^{2}\pi * 2r = 182\]
\[r ^{3}\pi=64 \]
\[r = \sqrt[3]{20.37}\]
r=2.73

Answer 5

OOh ok LOL Thank You so much :)

Answer 6

Numbers are weird, but that's the only way I see how it's done :)

Answer 7

as long as the answer n work r right that's all that matter in math LOL
