Closed drum

Find the total surface area of a closed cylindrical drum if it's diameter is 50 cm and height is 45 cm . (π= 3.14)

Correct result:

S =  10995.5743 cm2

Solution:

D=50 cm h=45 cm  r=D/2=50/2=25 cm S1=π r2=3.1416 2521963.4954 cm2 S2=π D h=3.1416 50 457068.5835 cm2  S=2 S1+S2=2 1963.4954+7068.5835=10995.5743 cm2=1.100104 cm2
