11 solid spheres of radius 3 m, 9 solid cylinder of radius 4 m, height 5 meter and 13 solid cones of radius 2 m, height 4 m are melted to form a bigger solid sphere. What is the radius of this bigger solid sphere in meters?
Total volume of the bigger sphere = [volume of 11 smaller spheres] + [volume of 9 cylinders] + [Volume of 13 cones].
(4/3)*π*r^3 = [11*(4/3)*π*(3)^3] + [9*π*(4)^2*5] + [13*π*(2)^2*4/3]
(4/3)*π*r^3 = [1244.07] + [2261.97] + [216.71]
(4/3)*π*r^3 = 3722.75
r = 9.61 meter.
The units are SI of course
