Question

The volume of a ball is 2145 cm? Work out the diameter of the ball.​

Answer 1

Answer:

Given: Volume of a ball = 2145cm

To find: Diameter of the ball.

Note, that ball is a sphere,

The Volume of a sphere is $\frac{4}{3}$ π r³

⇒ 2145 = $\frac{4}{3} \frac{22}{7} r*3$

if we simplify, we'll get cube root of 511.875 i.e., 7.99934890534cm

The Radius of the ball is 7.99934890534cm

Then the diameter of the ball is double of that.... i.e., 7.99934890534cm*2

We get, 15.9986978107cm as diameter
