Measuring cylinder

A measuring cylinder has a base radius of 35mm and a height of 500mm. Calculate the surface area wetted by the liquid if the level reaches a height of 35cm.

Correct answer:

S =  808.1747 cm2

Step-by-step explanation:

r=35 mm cm=35:10  cm=3.5 cm h=35 cm  S1=π r2=3.1416 3.5238.4845 cm2 S2=2π r h=2 3.1416 3.5 35769.6902 cm2  S=S1+S2=38.4845+769.6902=808.1747 cm2
