A triangle has three sides. Surface Area Areas of top and bottom Area of the side Surface Area 2Area of top perimeter of top height Surface Area 2pi r 2 2 pi r h In words the easiest way is to think of a can. In order to calculate its surface area or volume you must know the radius of the base and the length of the side.
Sphere Surface Area Formula and Sphere Volume Formula A sphere is a solid figure where every point on the surface is equidistant from the center of the sphere.
S r2 h2. The total surface area of hemisphere is equal to sum of half of surface area of sphere and area of its circular base. S A4 pi r2 Find the area of the great circle and multiply it by 4. In order to calculate its surface area or volume you must know the radius of the base and the length of the side.
