(B) .8/3πrcube
(C) .4πrcube
(D) .32/3πrcube

Answer 1

Here , we have the following information given -


The radius of a sphere is 2r .


To find -


Find the volume of that sphere .


Solution-


We know that -


For a sphere of radius a ,


Volume of the sphere -


¾ π a³


Here , the radius is 2r


Volume -


=> ¾ π ( 2 r ) ³



=> ¾ π 8 r³


=> 6 π r³ .


This is the required answer .

None of the given options are correct .
