Surface Area of Sphere: Consider a sphere having a radius of 4 centimeters. To calculate the surface area of this sphere, use the following formula: Surface Area = 4², where r is the radius of the sphere. Since r = 4, the surface area is: Surface Area = 4л(2)² =16 cm² Surface Area of Pyramid: Consider the pyramid having a triangle as a base. The base area of the pyramid is 20 square meters. the triangle's perimeter is 10 meters and the slant height of the pyramid is 10 meters. If 'b' is the base area, h is the slant height of the pyramid and p is the perimeter, then the surface area of the pyramid can be calculated as surface Area = b + (p+h) Thus, surface area, where b = 20, p = 10 and h = 10 is: surface Area = 20 + (10 + 10) =20 + 10 30 m²
