Calculate 3956

The rotating cylinder has a diameter of 14 cm and a surface of 1,186.92 cm square. Calculate the height of the cylinder.

Correct answer:

h =  19.9863 cm

Step-by-step explanation:

D=14 S=1186.92 r=D/2=14/2=7 S1=π r2=3.1416 72153.938 S2=S2 S1=1186.922 153.938879.0439 S2 = h   π   D h=S2/(π D)=879.0439/(3.1416 14)=19.9863 cm
