B. volume of cylinder will remain unchanged
C. volume of the cylinder will be halved
D. volume of cylinder will be
of the original volume
Answer :
we know that,
The volume of cylinder having base radius = r
And original height of cylinder = h
Volume of cylinder (v) = π × r2 × h
New height H = h and
New radius R = 2r (new radius = 2 times of original radius)
New volume of cylinder(V) = π × 4r2 × h = πr2h = v
Hence, the volume of new cylinder = the volume of original cylinder.
And the answer is (b).
