First, we need to convert the height to feet since the radius is given in feet. To do this, we divide the height in inches by 12 (since 1 foot = 12 inches).
105 inches ÷ 12 = 8.75 feet
The surface area of the can can be calculated using the formula for the lateral surface area of a cylinder:
Surface Area = 2πrh + 2πr^2
Surface Area = 2 * 3.14 * 0.5 * 8.75 + 2 * 3.14 * 0.5^2
Surface Area = 6.28 * 8.75 + 2 * 3.14 * 0.25
Surface Area = 54.95 + 1.57
Surface Area = 56.52 square feet
Therefore, the can's surface area is 56.52 square feet.
Mikayla has a can of paint that has a height of 105 inches and a radius of 0.5 feet. What is the can’s surface area in feet? Use 3.14 for π
