Adrian is painting the outside of a cylinder tire he plans to recycle as a planter. The tire has a radius of 4 feet and a height of 3 feet. In order to understand how much paint is needed, Adrian wants to know the surface area of the outside of the tire. How many square feet is the outside of the tire?
The formula to calculate the surface area of a cylinder is 2πr² + 2πrh.
Given that the radius (r) of the tire is 4 feet and the height (h) is 3 feet,
the surface area of the outside of the tire is 2π(4)² + 2π(4)(3),
which is equal to 2π(16) + 2π(12),
which simplifies to 32π + 24π.
Therefore, the surface area of the outside of the tire is 56π square feet.
