find the height and surface area of the right circular cylinder with the height equal to the diameter. Show work

anonymous · Answer

Height=2r
Volume-128pic

anonymous · Answer

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

anonymous · Answer

how do I solve for r?

anonymous · Answer

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