The formula for the surface area of a right circular cylinder is A = 2πr^2 + 2πrh, where r is the radius and h is the height.
Given that the radius is 1.5 feet and the length (height) is 20 feet, we can plug these values into the formula to solve for the surface area:
A = 2(3.14)(1.5)^2 + 2(3.14)(1.5)(20)
A = 2(3.14)(2.25) + 2(3.14)(30)
A = 6.28(2.25) + 6.28(30)
A = 14.13 + 188.4
A = 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 log is in the shape of a right circular cylinder. The length of the log is 20 feet, and the radius is 1.5 feet. Solve for the surface area. Use 3.14 for π.(1 point)
