<PRE><B>Question 1044328</B>
The cylinder:
20 diameter
30 height
Volume:
[Pi(20/2)^2]*30 = 9424.78
Area, assuming the cylinder has a base (not an open hole):
Area base: Pi(20/2)^2 = 314.16
Area of the side: 
(Pi*20)*30 = 1884.9
So, for the cylinder we have:
total volume = 9424.78
total area = 314.16+1884.9 = 2199.06
-----------------------------
The cone:
Height of 25 cm and a base diameter of 20cm
Volume:
[Pi(20/2)^2]*25/3 = 2617.99
Area, assuming the cone is connected to the cylinder so it has no base:
Pi(20/2)(20/2+sqrt(25^2+(20/10)^2 = 1102.07
Add the cone to the cylinder:
Volume cylinder 9424.78+2617.99 cone = 12,042.77
Area cylinder 2199.06+1102.07 cone = 3301.13
