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
The surface area of a cylinder is given by the formula:
Surface area = 2πr² + 2πrh
Where r is the radius and h is the height of the cylinder.
Plugging in the given values, we get:
Surface area = 2 * 3.14 * (4)² + 2 * 3.14 * 4 * 11
Surface area = 2 * 3.14 * 16 + 2 * 3.14 * 44
Surface area = 2 * 50.24 + 2 * 138.16
Surface area = 100.48 + 276.32
Surface area = 376.8 cm²
Therefore, the surface area of the soup can is 376.8 cm².
