Question

the diameter of a solid sphere is 6cm.it is melted and recast into a solod cylinder of height 4cm find the radius of cylinder

Answer 1

radius of sphere= 6/2=3
volume of sphere=volume of cylinder
or,4/3πr^3=πr^2h
or,113.14=12.57r^2
or, r^2= 9
or,r= 3 cm

Answer 2

Answer:

Step-by-step explanation:

Hey! Here is your answer

Volume of sphere = 4/3pie*rcube

Given diameter of sphere = 6cm

Therefore, radius = 3cm

= 4/3*pie*3*3*3

Volume of sphere = 4pie9cmcube

Volume of sphere = volume of cylinder

4pie9cmcube = pie*r^2h

4pie9 = pier^2*4

On solving this 4 and pie will be cut..and then,

r^2 = 9

r = 3cm
