How do you find the volume of a sphere?

Use the formula V = (4/3)πr³. Cube the radius, multiply by π, then multiply by 4/3.

What is the relationship between sphere volume and radius?

Volume is proportional to the cube of the radius. Doubling the radius increases the volume by a factor of 8 (2³).

How to Calculate the Volume of a Sphere

Formula

V = (4/3) × π × r³

Where:

V = Volume

π ≈ 3.14159

r = radius

Surface Area

SA = 4 × π × r²

Example Calculation

Find the volume of a sphere with radius 5.

01V = (4/3) × π × 5³
02= (4/3) × π × 125
03= (4/3) × 392.699
04≈ 523.5988
