To find the surface area of the steel rod, we first need to calculate the radius of the cylinder.
Given that the diameter is 0.50 inches, the radius (r) is half of the diameter: r = 0.50 / 2 = 0.25 inches.
The formula for the surface area of a cylinder is:
Surface Area = 2πrh + 2πr^2
where r is the radius and h is the height (length).
Given that the length is 36 inches, we can calculate the surface area using the formula and the value of π as 3.14:
Surface Area = 2 * 3.14 * 0.25 * 36 + 2 * 3.14 * 0.25^2
Surface Area = 6.28 * 0.25 * 36 + 2 * 3.14 * 0.0625
Surface Area = 6.28 * 9 + 2 * 0.19625
Surface Area = 56.52 + 0.3925
Surface Area = 56.9125
Therefore, the surface area of the steel rod is approximately 56.91 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 lenght is 36 inches what surface are? Use 3.14
