Answer 1

Answer: pls mark me brainliest

hope it is correct

Step-by-step explanation:

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.
