1. VOLUME
OF A SPHERE
LESSON 26

2. Volume of Spheres
A sphere is the set of all points that are a given distance from a given point, the center.
To calculate volume of a sphere, use the formula in the blue box. 4 3
V =
Volume is measured in cubic units.

3. Volume of Spheres
To find the volume of a sphere use the formula in the blue box. 4 3
V =
= (3.14)(6)3
= (678.24)
= units3 4 3
V = 4 3 4 3

4. YOU TRY!
To find the volume of a sphere use the formula in the blue box. 4 3

5. SOLUTION
To find the volume of a sphere use the formula in the blue box. 4 3
V =
= (3.14)(10)3
= (3140)
= cm3 4 3
V = 4 3 4 3

6. LETS REVIEW bh 2 V = Area of base x height Volume of Rectangular Prism
V = lwh
Volume of Rectangular Prism
V = Area of base x height
Volume of a Triangular Prism bh 2
V = (h) 1 3
V = Area of base x height
Volume of a Pyramid 1 3
V = Volume of cylinder
V = h
Volume of a Cone 1 3

7. LETS REVIEW 4 3 V = V = Area of base x height V = h Volume of Cylinder
