If a sphere has its radius as 8cm find the surface area of the sphere and the volume of the sphere
Surface Area of a sphere = 4πr^2
Volume of a sphere = 4/3 * π * r^3
Given that the radius (r) of the sphere is 8 cm,
Surface Area = 4 * π * 8^2
Surface Area = 4 * π * 64
Surface Area = 256π
Surface Area ≈ 804.25 cm^2
Volume = 4/3 * π * 8^3
Volume = 4/3 * π * 512
Volume = 682.67π
Volume ≈ 2144 cm^3
Therefore, the surface area of the sphere is approximately 804.25 cm^2 and the volume of the sphere is approximately 2144 cm^3.
