What is the total surface area of the cylinder? radius is 2.5 meters and height is 7 meters.
Use 3.14 for pi.
The total surface area of a cylinder is calculated by finding the sum of the areas of its curved surface (lateral surface area) and its two circular bases.
The formula for the lateral surface area of a cylinder is given by: LSA = 2πrh, where r is the radius and h is the height.
The formula for the area of a circle (base of the cylinder) is given by: A = πr^2, where r is the radius.
Given that the radius (r) is 2.5 meters and the height (h) is 7 meters, we can calculate:
Curved Surface Area (LSA) = 2 * 3.14 * 2.5 * 7 = 109.92 square meters
Base Area (A) = 3.14 * (2.5)^2 = 19.625 square meters
Total Surface Area (TSA) = LSA + 2A = 109.92 + 2 * 19.625 = 109.92 + 39.25 = 149.17 square meters
Therefore, the total surface area of the cylinder is approximately 149.17 square meters.
