The Z value is 0.


What is the lateral surface area of a right cylinder?

The lateral area of a right cylinder is curved surface that connects the two bases. The surface area is the total area of the curved surface and the bases.Lateral Area: The lateral area of a right cylinder with radius r and height h is L = 2pirh.Surface Area: The surface area of a right cylinder with lateral area L and base area B is S = L + 2B, or S = 2pirh + 2pir^2.


What is the surface area of a right cylinder where the radius is 8 and the height is 14?

The total surface area is 1,105.84 units2The lateral surface area is 703.72 units2


How do you figure what percent of the total area one small area is?

There are many methods to do this. One is to calculate the are of the enitire figure. Then figure out the area of the smaller area. Then divide the smaller figure's area by the larger figure's area and change the answer to a percent. For example, if you were asked to figure out what percent of square A with sides measuring 5 cm was covered by square B (which is completely inside of square A) with sides of 1 cm. 1. Calculate the are of square A. 25 cm2 2. Calculate the are of square B. 1 cm2 3. Divide square B by square A. 1/25 or 0.04 4. Convert to a percent. 4%


What is the lateral and surface area of a right prism?

The lateral area of a prism is the sum of the areas of all the lateral faces. A lateral face is not a base. The surface area is the total area of all faces.Lateral Area: The lateral area of a right prism with base perimeter P and height h is L=Ph.Surface Area: The surface area of a right prism with lateral area L and base area is B is S = L + 2B, or S = Ph + 2B.
