Question

A milk can is in the shape of a cylinder. If its height is of 10 inch and the radius is of 5 inch, then what
is the surface area of this can (use π = 3.14)?

Answer 1

Given,

Height of milk can = 10 inches

The radius of milk can = 5 inches

To Find,

The surface area of the milk can.

Solution,

Since the shape of the milk can is that of a cylinder

Therefore, the formula for calculating the surface area of the cylinder is

Surface area = 2 π r h + 2 π r²

                      = 2*3.14*5*10 + 2*3.14*5*5

                       = 471 inches sq.

Hence, the surface area of the milk can is 471 inches sq.
