Consolidation phase
Calculate and conclude

As shown in the picture, calculate the surface area, volume, and weight of the sphere if its specific weight is γ=78 N/dm3, where it is a semicircle of radius 50 cm and 70 cm. What do you conclude? Do the values increase with an increase in radius or not? Why?
