The radius of a sphere is 2r, then its volume will be

(A) \frac{4}{3}\pi r^{3}

(B) 4\pi r^{3}

(C) \frac{8\pi r^{3}}{3}

(D) \frac{32}{3}\pi r^{3}

Answers (1)

We know that volume of a sphere is given as  \frac{4}{3}\pi r^{3} where r is the radius of the sphere.

In this question it is given that the Radius of sphere is 2r

So, Volume of sphere will be equal to:

=\frac{4}{3}\pi \left ( 2r \right )^{3}

=\frac{4\times 8}{3}\pi \left ( r \right )^{3}

=\frac{32}{3}\pi r^{3}

So, option (D) is the correct.
