A cylindrical vessel of a certain height and radius can hold 30 liters of water in it when filled to the brim. All the water in the cylindrical vessel is transferred to a spherical vessel. If the height and radius of the cylindrical vessel is the same as the radius of the spherical vessel, what percentage of the capacity of the spherical vessel will remain empty after the transfer?	Select the correct option.
A) 0%	B) 16.67%	C) 25%	D) 33.33%	E) 50%
Let R and H be the radius and height of the cylinder.   Let r be the radius of the sphere.   Volume of cylinder = Vc = π∗R2∗Hπ∗R2∗H = 30---&gt; As both radius and height of the cylinder are equal to the radius of the sphere ---&gt; R=H=r ---&gt;π∗r3π∗r3 = 30   Additionally, volume of the sphere = Vs =4π∗r334π∗r33 = 4/3*30=
