Question

The andius of uphore is R. then find its volume
​

Answer 1

The volume of the sphere is$\frac{704}{21} \times r^{3}$

.

Step-by-step explanation:

We are given that the radius of the sphere is 2r and we have to find its volume.

As we know that the volume of a sphere is given by the following formula;

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

Here, r = radius of the sphere

Now, it is stated that the radius of the sphere is 2r, i.e;

So, the volume of the sphere = $\frac{4}{3}\pi \times (2r)^{3}$

$= \frac{4}{3}\pi$ $\times 8r^{3}$

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

$= \frac{704}{21} \times r^{3}$

Hence, the volume of the sphere is $\frac{704}{21} \times r^{3}$
