Martha has a soup can in the shape of a cylinder with a height of 11 cm and radius of 4 cm. What is the surface area of the can? Use 3.14 for π and round to the nearest tenth.

1 answer

Let's first calculate the surface area of the can.

The formula for finding the surface area of a cylinder is given by:

Surface Area = 2πr(r + h)

Where r is the radius and h is the height of the cylinder.

Given:
r = 4 cm
h = 11 cm

Substitute these values into the formula:

Surface Area = 2 * 3.14 * 4(4 + 11)
Surface Area = 2 * 3.14 * 4(15)
Surface Area = 2 * 3.14 * 60
Surface Area = 376.8

Therefore, the surface area of the can is 376.8 square cm. Rounded to the nearest tenth, the surface area is 376.8 square cm.
