A riser in the shape of a sphere is to be designed for a sand casting mold. The casting is a rectangular plate,
with length = 100 mm, width = 50 mm, and thickness = 10 mm. If the total solidification time of the casting
itself is known to be 2.5 min, determine the diameter of the riser so that it will take 20% longer for the riser
to solidify.
