What is

What is the height of a cylinder whose surface size is 602.88 cm2 and the area of its shell is 376.8 cm2?

Correct answer:

h =  10 cm

Step-by-step explanation:

S=602.88 cm2 S1=376.8 cm2  S = S1 + 2 S2  S2=(SS1)/2=(602.88376.8)/2=252826=113.04 cm2  S2 = π r2  r=S2/π=113.04/3.14165.9985 cm  S1 = 2 π r h  h=2π rS1=2 3.1416 5.9985376.8=10 cm
