Question

if the radius of the sphere is halved then find it's new volume​

Answer 1

Answer:

Vol. of sphere = 4/3πr 3

New vol: 4/3xπx(r/2) 3

= 4/24πr^3

vol. Will be reduced to 1/8

Answer 2

The new volume is $0.523r^3$

Step-by-step explanation:

Let the radius of sphere be r

We are given that the radius is halved

So, new radius =$\frac{r}{2}$

Volume of sphere =$\frac{4}{3} \pi r^3$

Volume of sphere = $\frac{4}{3} \times \frac{22}{7} \times (\frac{r}{2})^3$

Volume of sphere = $\frac{4}{3} \times \frac{22}{7} \times \frac{r^3}{8}$

Volume of sphere =$0.523r^3$

Hence The new volume is $0.523r^3$
