12 solid spheres of the same size are made by melting a solid metallic cylinder of base radius 1cm and height 1/3 of 48cm. The radius of each sphere is :
A) 4cm B) 3 cm C) 2cm D) 1cm
plz explain with steps............12 small spherical spheres have been recasted from a bigger cylinder
We have
Radius of cylinder (R) = 1 cm
Height of cylinder (h) = 16 cm
Let the radius of the small spheres be r
So,
12 (Volume of small sphere) = Volume of cylinder
