Answer»

Given, Cylinder radius r1 = 35/2 cm, height h1 = 32 cm

Cone radius r2 = 4/2 = 2 cm, height h2 = 7 cm

Volume of cylinder V1= pi*r1^2*h1= pi*35/2*35/2*32

Volume of cone V2= 1/3*pi*r2^2*h2= 1/3*pi*2*2*7

Let number of cones can be filled = n

Then,n*V2 = V1n = pi*35/2*35/2*32 / 1/3*pi*2*2*7 = 3*5*35*2 = 30*35 = 1050

Therefore, Number of cones can be filled = 1050
