So, to solve this we have a Circular cylinder and half a Sphere.

Total Volume 402+134 = 536 ft³  <- Answer

Calclulations
Answer:

r = 4 in
h = 8 in
V = 402.124 in³
L = 201.062 in²
T = 50.2655 in²
B = 50.2655 in²
A = 301.593 in2
Agenda 
r = radius
h = height
V = volume
L = lateral surface area
T = top surface area 
B = base surface area 
A = total surface area
π = pi = 3.14159
√ = square root

Formula cylinder:V = πr²h
The answer for the sphere

r = 4 ft
V = 268 ft/2=134 ft³
A = 201 ft²
C = 25.1 ft

Agenda
r = radius
V = volume
A = surface area
C = circumference
π = pi = 3.14159
√ = square root

Formula:

Volume of a sphere:V = (4/3)πr³
