Question

find the volume of sphere of radius 2r

Answer 1

hey here is your answer !!.☺

volume = 4/3 *π*r³
= 4/3*22/7*8r³
= 88*8r³/21
= 176r³/21 unit ³


hope this helps.. :-)

Answer 2

Answer:

Step-by-step explanation:

Given: The radius of sphere is 2r.

To find: The volume of sphere.

Solution:

It is given that the radius of sphere is 2r, then the volume of sphere is given as:

$V=\frac{4}{3}{\pi}r^3$, where r is the radius of the sphere

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

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

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

$V=33.49r^3$
