I assume you mean the surface area, since a square pyramid is 3-dimensional. For a right square pyramid with base side length s and slant height L, the total surface area is the area of the square base with side length s, plus the total area of four triangles each with base s and altitude L. So the total surface area is s^2 + 4(1/2)(sL) = s^2 ... A hemisphere is one-half a sphere, its surface area including the circular cross section. Examples of 3D solid shapes. A prism is a 3D solid with two congruent, opposite faces (bases) with all other faces parallelograms of some sort. Examples of prisms are cubes and triangular, rectangular, hexagonal and octagonal prisms.A sphere contains infinitely many great circles. Each great circle is considered a plane of symmetry since it divides the sphere into two equal parts. This means that a sphere has infinitely many planes of symmetry. Volume of a sphere. The volume, V, of a sphere is. where r is the radius of the sphere. Surface area of a sphereThe surface area is half of a sphere. Substituting the numbers into the formula for calculating surface area, we can calculate the following. 4 π × 4 2 × 1 2 = 32 π. We must also add the area of the cross-section of the hemisphere.
