Volume and surface

Calculate the volume and surface area of the cylinder when the cylinder height and base diameter is in a ratio of 3:4 and the area of the cylinder jacket is 24 dm2.

Correct answer:

V =  19.15 dm3
S =  40 dm2

Step-by-step explanation:

24=2πrh  h:D=3:4 h:r=3:2 2h=3r 24=3πr2 r=8/π=1.596 dm h=32r=2.394 dm V=πr2h=19.15 dm3
S=24+2πr2=40 dm2
