Question

If the radius of a sphere is 2r, then its volume is :
a) 4/3πr^3. b) 4πr^3. c)8/3πr^3. d) 32/3πr^3​

Answer 1

Answer:

radius = 2r

volume= 4/3πr^3

=4/3π(2r)^3

= 4/3π(8)r^3

=32πr^3

so d. is correct

Answer 2

Answer:

$\large\boxed{\sf{(d)\;\;\dfrac{32}{3}\pi{r}^{3}}}$

Step-by-step explanation:

Given that there is a sphere.

Radius = 2r

To find the volume:

$=>v=\dfrac{4}{3}\pi{(2r)}^{3}\\\\=>v=\dfrac{4}{3}\pi\times8{r}^{3}\\\\=>v=\dfrac{32}{3}\pi{r}^{3}$

Hence, option (d) is Correct
