Calculating Volumes of Cone, Cylinder, and Sphere

The video tutorial explains how to calculate the volume of three geometric shapes: a cone, a cylinder, and a sphere. It begins by introducing the formulas for each shape's volume, where 'R' represents the radius and 'H' the height. The tutorial then provides step-by-step examples for each shape, demonstrating how to apply the formulas using specific dimensions. The examples include calculating the volume of a cone with a radius of 5 and height of 12, a cylinder with a radius of 8 and height of 7, and a sphere with a radius of 6. The video concludes by summarizing the process of solving for volume in these shapes.

What is the formula to calculate the volume of a cylinder?

• V = πr^2h

• V = πr^3

• V = 1/3πr^2h

• V = 4/3πr^3
