Calculate 24011

There is a cylinder with a base radius of 3 cm and a height of 12 cm. Calculate
a) cylinder surface
b) cylinder volume

Correct answer:

S =  282.7433 cm2
V =  339.292 cm3

Step-by-step explanation:

r=3 cm h=12 cm  S1=π r2=3.1416 3228.2743 cm2  S=2 S1+2π r h=2 28.2743+2 3.1416 3 12=282.7433 cm2
V=S1 h=28.2743 12=339.292 cm3
