Answer :
volume of cyl.=πr²h
=22/7*9*9*4000
=1018285.71cm³
volume of sphere=4/3πr³
=4/3*22/7*3*3*3
=113.14
no. of spheres =1018285.71/113.14
=9000
=22/7*9*9*4000
=1018285.71cm³
volume of sphere=4/3πr³
=4/3*22/7*3*3*3
=113.14
no. of spheres =1018285.71/113.14
=9000
Volume of sphere = [tex] \frac{4}{3} [/tex] π [tex] r^{3} [/tex]
= [tex] \frac{4}{3} [/tex] * [tex] \frac{22}{7} [/tex] * 3 * 3 * 3
=113.14 [tex] cm^{3} [/tex]
h = 40m = 4000cm
Volume of cylinder = π [tex] r^{2} [/tex] h
=1018285.71 [tex] cm^{3} [/tex]
Number of spheres = [tex] \frac{volume of cylinder}{volume of sphere} [/tex]
=[tex] \frac{1018285.71}{113.14} [/tex]
= 9000 spheres.
= [tex] \frac{4}{3} [/tex] * [tex] \frac{22}{7} [/tex] * 3 * 3 * 3
=113.14 [tex] cm^{3} [/tex]
h = 40m = 4000cm
Volume of cylinder = π [tex] r^{2} [/tex] h
=1018285.71 [tex] cm^{3} [/tex]
Number of spheres = [tex] \frac{volume of cylinder}{volume of sphere} [/tex]
=[tex] \frac{1018285.71}{113.14} [/tex]
= 9000 spheres.
