Surface Area of Prisms

"Surface area is a two-dimensional property of a three-dimensional figure. Prisms have two congruent, parallel bases separated by lateral faces. Lateral faces are congruent rectangles with a height e ...

Surface Area of Joined Solids

"Surface area is a two-dimensional property of a three-dimensional figure. When solids are joined together, such as a hemisphere on a cone, the surface area of the connecting circle is not included in ...

Surface Area of Cylinders

"Surface area is a two-dimensional property of a three-dimensional figure. Cylinders are similar to prisms in that they have congruent, parallel bases, except cylinders have circles as their bases. ...

Surface Area of a Sphere

In general, surface area is the sum of all the shapes that cover the surface of an object. To calculate the surface area of a sphere we multiply 4 by pi by the radius of the sphere squared. Given this ...

Surface Area of a Pyramid

"Surface area is a two-dimensional property of a three-dimensional figure. Pyramids have polygonal bases and triangular faces, which are congruent if the base is regular. To find the total surface a ...

Surface Area of a Cone

"Surface area is a two-dimensional property of a three-dimensional figure. Cones are similar to pyramids, except they have a circular base instead of a polygonal base. Therefore, the surface area of a ...

Approximate Area

"When finding the area under a curve for a region, it is often easiest to approximate area using a summation series. This approximation is a summation of areas of rectangles. The rectangles can be eit ...
