Question 755121: a paint roller has a lateral area of 5 pi. what is the area covered if the roller makes 16 revolutions?
i know that a paint roller is a cylinder.
lateral area = 2 pi r h (r= radius) (h=height) leave answer in terms of pi
total area = lateral area + 2 pi r^2

What you say is true.
Area covered = 16*lateral area
