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. And 188.4 is wrong

1 answer

To find the surface area of a cylinder, we need to calculate the area of the two circular bases and the lateral surface area.

The formula for the surface area of a cylinder is:
Surface Area = 2πr(r + h), where r is the radius and h is the height.

Given:
r = 4 cm
h = 11 cm
π ≈ 3.14

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 cm^2

Therefore, the surface area of the soup can is approximately 376.8 cm^2.
