Question

A metallic sphere of total volume π is melted and recast into the shape of a right circular cylinder of radius 0.5 cm.​

Answer 1

volume of sphere = pi cm cube

4/3pi r3 = pi

4/3 r3 = 1

volume of cylinder = pi r2 h

pi 0.25 h= pi

25h/100 = 1

25h=100

h=100/25=4

height of cylinder = 4 cm
