How does the volume of a cylinder change when its diameter is halved

Mathematics
1 answer:
Ivahew [28]3 years ago
7 0

The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and <span>h </span>is the height of the cylinder.

Also<span> r=d/2</span> , where d is the diameter of the cylinder.

Therefore if the diameter is halved, the radius also gets halved ,i.e., it becomes r/2. Therefore the new volume =<span> π(r/2)²h</span>

=π(r²/4)h

<span>=(1/4) πr²h</span>

<span>
</span>
