Surface of the cylinder

Calculate the surface of the cylinder for which the shell area is Spl = 20 cm2 and the height v = 3.5 cm.

Correct answer:

S =  25.1969 cm2

Step-by-step explanation:

S1=20 cm2 v=3.5 cm  S1 = 2 π r v  r=S1/(2π v)=20/(2 3.1416 3.5)0.9095 cm  S2=π r2=3.1416 0.909522.5984 cm2  S=S1+2 S2=20+2 2.5984=25.1969 cm2
