the value of pi.
The formula for finding the surface area of a right circular cylinder is:
Surface Area = 2πr(r + h)
Given that the diameter is 0.50 inches, the radius (r) would be half of that:
r = 0.50 / 2 = 0.25 inches
The height (h) of the cylinder is given as 36 inches.
Plugging in the values, we get:
Surface Area = 2 * 3.14 * 0.25 * (0.25 + 36)
Surface Area = 6.28 * 0.25 * 36.25
Surface Area = 6.28 * 9.0625
Surface Area = 57.0305 square inches
Therefore, the surface area of the steel rod is 57.03 square 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
