The rectangle ABCD | AB | is given = 8 cm, | BC | = 4 cm. Determine the height and radius of the cylinder, which is created by rotating the rectangle around the line AB.

Correct answer:

h =  8 cm
r =  4 cm
V =  402.1239 cm3

Step-by-step explanation:

a=8 cm b=4 cm  h=a=8=8 cm
r=b=4=4 cm
V=π r2 h=3.1416 42 8=402.1239 cm3
