how do you find the volume of a sphere

To find the volume of a sphere , you use the formula:

V=43πr3V=\frac{4}{3}\pi r^3V=34​πr3

Explanation:

• V is the volume of the sphere.
• r is the radius of the sphere.
• π (pi) is approximately 3.14159.

Steps to find the volume:

1. Measure the radius (r) of the sphere.
2. Cube the radius: r3=r×r×rr^3=r\times r\times rr3=r×r×r.
3. Multiply by π\pi π.
4. Multiply by 43\frac{4}{3}34​.

Example:

If the radius of a sphere is 3 units:

V=43×π×33=43×π×27=36π≈113.1 cubic unitsV=\frac{4}{3}\times \pi \times 3^3=\frac{4}{3}\times \pi \times 27=36\pi \approx 113.1\text{ cubic units}V=34​×π×33=34​×π×27=36π≈113.1 cubic units
