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
Height=2r Volume-128pic
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
how do I solve for r?
\[r ^{2}\pi * 2r = 182\] \[r ^{3}\pi=64 \] \[r = \sqrt[3]{20.37}\] r=2.73
OOh ok LOL Thank You so much :)
Numbers are weird, but that's the only way I see how it's done :)
as long as the answer n work r right that's all that matter in math LOL
