what is the formula to finding the total surface area of a rhomboid?!
Total surface area = 1847.26 sq cm.
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
Surface area is the total space that a three-dimensional object occupies. When using the mathematical formula for its shape you get the surface area measurement.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
