Calculation of the Volume and Surface Area of a Sphere

To find the volume and surface area of a sphere with a radius of 2.5 meters, we can use the following formulas:

Volume of a Sphere (V): V = (4/3) * π * r^3 Surface Area of a Sphere (S): S = 4 * π * r^2

Substituting the given radius of 2.5 meters into the formulas, we can calculate the volume and surface area.

Calculation:

Volume of the Sphere (V): V = (4/3) * π * (2.5)^3 V ≈ 65.45 cubic meters

Surface Area of the Sphere (S): S = 4 * π * (2.5)^2 S ≈ 78.54 square meters

Therefore, the volume of the sphere is approximately 65.45 cubic meters, and the surface area is approximately 78.54 square meters.
