Question

Cones 3cm high and 3.5cm radius are made by melting sphere of 10.5cm radii find no. of cone are formed

Answer 1

Answer:

Step-by-step explanation:

hey buddy!!

given

radius of sphere = 10.5 cm

radius of cone = 3.5 cm

height of cone = 3 cm

So, Number of cones formed is

[4/3 pi r³] / [1/3  pi r²h]

=4 r³/r²h

=(4*10.5*10.5*10.5) / (3.5*3.5*3)

=4*3*3*3.5

=9*14

=126 cones[ Ans]

hope it helps!!!
