Learn how to determine the volume of a sphere

The video tutorial explains the concept of a great circle on a sphere, using the Earth as an example. It describes how a great circle is the largest possible circle that can be drawn on a sphere, dividing it into two equal hemispheres. The tutorial then demonstrates how to calculate the radius of a sphere using the area of a great circle and subsequently find the surface area of the sphere. The process involves using the formula for the area of a circle (πR²) and the surface area formula for a sphere (4πR²).
