Question

cones 3 cm high and of 3.5 CM radii are made by melting of sphere of 10.5 CM radius. find the number of cones

Answer 1

given
radious of sphere = 10.5cm
radious of cone = 3.5cm
hight of cone = 3cm
So, Number of cones formed is
[4/3¶r³] / [1/3¶r²h]
=4r³/r²h
=(4*10.5*10.5*10.5) / (3.5*3.5*3)
=4*3*3*3.5
=9*14
=126 cones[ Ans]
