Question

the diameter of metallic sphere is 6 cm. the sphere malted and drawn from into a wire of uniform cross-section .if the length of the wire is 36 m. find the radiu

Answer 1

volume of sphere=volume of wire

4/3πr^3=πr^2h

simplifying further,

you get r=1

Answer 2

Answer:

Step-by-step explanation:

Radius of sphere = 3 cm  

Now volume of sphere = 43π(3)3  

Now sphere is melted and draw into wire  

Volume of sphere = Volume of cylinder formed  

43π(3)3=πr2×3600  

36π=r2x3600π  

l=r2x100  

r2=1/100  

r=1/10cm

=0.1cm
