The formula for the surface area of a right circular cylinder is 2πr(r + h), where r is the radius and h is the height (or length in this case).
Given that the diameter is 0.50 inches, the radius (r) is half of that, so r = 0.25 inches. The length (h) is 36 inches.
Plugging these values into the formula:
Surface area = 2(3.14)(0.25)(0.25 + 36)
Surface area = 2(3.14)(0.25)(36.25)
Surface area = 2(3.14)(9.0625)
Surface area = 2(28.5545)
Surface area = 56.91 inches
Therefore, the correct answer is 56.91 inches.
Maria wants to find the surface area of a steel rod that is in the shape of a right circular cylinder. The diameter is 0.50 inches and the length is 36 inches. What is the surface area use 3.14 for rr is the answer 0.39 inches, 56.52 inches, 56.91 inches or 114.61 inches
