Find the surface area of a cylinder with a diameter of 12 inches and height of 10 inches. Use the approximation of 3.14 for pi

Answer 1

The formula for the surface area of a cylinder is given by 2πrh + 2πr^2, where r is the radius and h is the height.

Given that the diameter of the cylinder is 12 inches, the radius would be half of that, which is 12/2 = 6 inches.

Using the approximation of pi as 3.14, the surface area can be calculated as:
2(3.14)(6)(10) + 2(3.14)(6)^2
= 2(3.14)(60) + 2(3.14)(36)
= 376.8 + 226.08
= 602.88 square inches.

Therefore, the surface area of the cylinder is approximately 602.88 square inches.
