Question

if the metallic cylinder of height 4 cm and radius 3 cm is melted and recast into a spares then find the radius of the sphere​

Answer 1

Answer:

Step-by-step explanation:

Cylinder

r=3cm

h=4cm

If it is recasted into sphere than

πr²h=4πR³/3

(3) ²×4=4R³/3

9×3=R³

³√3×3×3=R³

3cm=R

Answer 2

Answer:

h=4cm,r=3cm

volume of cylinder =22÷7×9×4=792÷7

volume of spare =22÷7×4÷3×r

792÷7=22÷7×4÷3×r

792÷7=88÷7×3×r

792÷7×7×3÷88

27=r
