Volume of 2 spheres with radius 3m = 113.1*2 = 226.2m³
Volume of 3 Cylinders of radius 2m and height 3m = 37.7*3 = 113.1m³
Volume of 2 solid cones of radius 2m, height 4m =16.76*2 = 33.51m³
Total volume of the larger sphere after melting = 226.2+113.1+33.51 = 372.81m³
Therefore the Radius of this larger Sphere = 4.46m.
