Question

A shot put ball is having
a radius of 2.1 cm find the
Volume of shotput​

Answer 1

Step-by-step explanation:

Answer

Since the shot-put is a solid sphere made of metal and its mass is equal to the product of its volume and density, we need to find the volume of the sphere.

Now, volume of the sphere =

of metal is 7.8g

Therefore, mass of the shot-put =7.8×493g

=3845.44g=3.85kg (nearly)
