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
