If the diameter of a sphere is reduced to its half, then the volume would be:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. reduced by of the former volume.
Given that
If the diameter of a sphere is reduced to its half
Volume of a sphere V = 4/3 π r³ = πd3/6
The volume of a sphere ∝ diameter3
New volume = (1/2)3 × former volume = 1/8 of the former volume
