Question

a metallic sphere of radius 9 cm is melted and then recast into small cones of radius 3 cm and height 6 cm find the number of cones does formed

Answer 1

hii mate

here is ur answer

as the sphere is recasted into cones

therefore the volume will not change at all

therefore volume of the sphere is equal to the volume of all cones

and we can find the volume of one cone as it's dimensions are given .

and divide the volume of sphere by volume of one cone to get the no. of cones.

I hope u like it then please mark it as brainliest.....
