Question

A sphere has a radius of 8cm.Find its volume​

Answer 1

sphere

Explanation:

volume of a sphere = 4/3πr³

= 4/3*22/7 * 8³

= 2145.5

Volume of a Sphere Formula:
`\displaystyle V = (4 \pi)/(3)r^3`

• r is radius

Explanation:

Step 1: Define

Identify variables

r = 8 cm

Step 2: Find Volume

1. Substitute in variables [Volume of a Sphere Formula]:
   `\displaystyle V = (4 \pi)/(3)(8 \ cm)^3`
2. Evaluate exponents:
   `\displaystyle V = (4 \pi)/(3)(512 \ cm^3)`
3. Multiply:
   `\displaystyle V = (2048 \pi)/(3) \ cm^3`
