Answer: (a) 2 : 3
(b) 4 :1
Step-by-step explanation:
The Volume of a sphere is given as
and the volume of a cylinder is given as
h
The ration of their volume is the same as Volume of Sphere : Volume of Cylinder , which gives
:
h
recall that they have the same radius and the height of the cylinder is 2r , taking this into consideration, we have
:
(2r)
which gives 4 : 6 = 2 :3
(b) The area of a sphere is 4
and the surface area of the circular cylinder is
The ratio then gives
4
:
,which gives
4 : 1
