the volume of Sphere will be 36 Pi R cube

Naresh5551: volume of sphere =4/3πr³
Naresh5551: on putting the value of radius we get. ...
Naresh5551: 4/3π*(3r) ³
Naresh5551: 4/3*π*9r³
Naresh5551: 3will cancel out 9by 3
Naresh5551: we get
Naresh5551: sorry it's 4/3 π*(√3r) ³
Naresh5551: so 4/3 π*3 r³
Naresh5551: so tha final answer is 4πr³
Anjali999: but the actual answer is 4 underroot3 pi r³

R=_/3 r
V=4/3 × (pi)×R^3
=4/3×(pi)×(_/3r)^3
=4/3×(pi)×3_/3×r^3
=4 (pi)_/3 r3
