The cylinder has a radius of 4 feet and a height of 3 feet Adrian wants to paint all around the outside of the cylinder, including the top bottom pieces in order to understand how much paint is needed. He wants to know the surface area of the outside of the cylinder what is the surface area of the cylinder measured in square feet is 3.14 for pie and round your answer to the nearest 10th
The formula for the surface area (SA) of a cylinder is:
SA = 2πr(r+h)
Given that the radius (r) is 4 feet and the height (h) is 3 feet, we can calculate the surface area by substituting these values into the formula:
SA = 2π(4)(4+3)
SA = 2π(4)(7)
SA = 2π(28)
SA ≈ 2(3.14)(28)
SA ≈ 175.84
Therefore, the surface area of the cylinder is approximately 175.84 square feet. Rounding to the nearest tenth, the surface area is 175.8 square feet.
