The volume will remain same. this us as follows.
let radius of cylinder = 4 cm.
volume= 22/7 * 4*4*7
=352 cm cube.
if radius is halved= 4/2 = 2cm.
height is doubled= 7*2=
volume = 22/7*2*2*14
volume= 176 cm cube.
it implies that the volume will be halved.
name the questions i'll find them.
the surface area of a sphere is of radius 5 cm is five times the curved surface are of a conee
and internal and external diameters of a hollow hemispherical vessel...
please tell me the formula of surface area of cone.
(pi)(r)(r + l)
