Find the volume and total area of the sphere which circumscribes a cylinder of revolution whose altitude and diameter are each 6 inches.
Volume of the sphere:
Total surface area of the sphere:
Good Day! Will you tell me how the formula for the volume of the sphere is derived and also for the formula of the total surface area? thanks!!
1. Volume of sphere by integration.
2. Surface area of the sphere by integration
You can also find the formulas for volume and surface area of the sphere by Pappus' theorem.
