Measuring the volume of a sphere is fun and easy. Follow these steps and you’ll become a pro!

## What is a Sphere?

A sphere is a round 3D shape. It’s like a ball. Every point on the sphere’s surface is the same distance from its center.

## Volume of a Sphere

Volume is the amount of space a shape takes up. For a sphere, we can calculate it with a special formula.

### Formula To Measure The Volume Of A Sphere

The formula to measure the volume of a sphere is:

Here, π (pi) is about 3.14. The letter “r” stands for the radius of the sphere.

## What is the Radius?

The radius is the distance from the center of the sphere to its surface. You need the radius to calculate the volume.

## Steps to Measure the Volume of a Sphere

**Find the radius:**Measure from the center to the surface.**Cubing the radius:**Multiply the radius by itself three times.**Multiply by π:**Use 3.14 for π.**Apply the formula:**Plug the numbers into the formula.

### Example Calculation

Let’s measure the volume of a sphere with a radius of 3 cm.

**Step 1:**Radius (r) = 3 cm**Step 2:**Cubing the radius = 3 × 3 × 3 = 27 cm³**Step 3:**Multiply by π = 27 × 3.14 = 84.78 cm³**Step 4:**Apply the formula = (4/3) × 84.78 = 113.04 cm³

So, the volume of the sphere is 113.04 cm³.
