Cylinder height

Calculate the height of the cylinder and its surface is 2500 dm2 and the bases have a diameter 5dm.

Correct result:

h =  156.6549 dm

Solution:

S=2500 dm2 D=5 dm r=D/2=5/2=52=2.5 dm  S1=π r2=3.1416 2.5219.635 dm2  S2=S2 S1=25002 19.6352460.7301 dm2  o=π D=3.1416 515.708 dm  h=S2/o=2460.7301/15.708=156.6549 dm
