Answer 2

Answer:

A cylinder has 3 surfaces --- Two circular surfaces (top and base) and one curved lateral surface.

Step-by-step explanation:

1 curved face

Another word for corners is vertices. A face is the part of the shape that has the largest surface area – some can be flat, some can be curved e.g. a cube has 6 flat faces whereas a cylinder has 2 flat faces and 1 curved face.

B is the area of a base and h is the height of the cylinder. For cylinders the bases are always circles, so B will always be π r2. r=4 inches and h=16 inches.
