Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.

A cone with a diameter of 18km and a slant height of 20.1km has a total surface area of about 822.78km2
To calculate the surface area of a cylinder, you need to add the areas of the two bases (top and bottom) and the lateral surface area. The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height. Given the radius is 7cm (half of the diameter) and the height is 18cm, the lateral surface area is 2 * π * 7 * 18 = 252π cm². The total surface area is the sum of the lateral surface area and the areas of the two bases, which is 252π + 2(πr²) = 252π + 2(π*7²) = 252π + 98π = 350π cm², or approximately 1099.65 cm².
