The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Given that the radius (r) is 1.5 feet and the height (h) is 20 feet, we can now plug these values into the formula:
Surface Area = 2 * 3.14 * (1.5)^2 + 2 * 3.14 * 1.5 * 20
Surface Area = 2 * 3.14 * 2.25 + 2 * 3.14 * 1.5 * 20
Surface Area = 2 * 3.14 * 2.25 + 3.14 * 1.5 * 40
Surface Area = 2 * 3.14 * 2.25 + 3.14 * 60
Surface Area = 14.13 + 188.4
Surface Area = 202.53
Therefore, the surface area of the log is 202.53 square feet.
Natalia is getting ready to cut a log up into smaller pieces. The long in the shape of the right circular cylinder length is 20 feet and the radius is 1.5 feet solve for the surface area use 3.14 for pi
