Question

how many spheres of radius 0.5cm can be prepared by melting a metal cylinder having diameter 4 cm abd height 10cm.​

Answer 1

SOLUTION___(•‿•)

Given,

Height of the cylinder melt= 10cm

Diameter of the cylinder= 4cm

Radius of the sphere= 0.5cm

Volume of the cylinder= 22/7×0.5×0.5×10

Now,

let the number of sphere= n

Volume of the sphere= 4/3×22/7×0.5×0.5×0.5

So,

Volume of all the sphere= volume of the cylinder

= n×4/3×22/7×0.5×0.5×0.5=22/7×0.5×0.5×10

= n×4/3×0.5=10

= n×2/3=10

= n= 10×3/2

=n= 30/2

=n= 15 ans.
