Answer:
V = 50.2654825 ft³
Explanation:
V=πr²h /3
Diameter is 4 ft thus radius is 2 ft.
radius r = 2 ft
height h = 12 ft
slant height s = 12.1655251 ft
volume V = 50.2654825 ft³
lateral surface area L = 76.4382483 ft²
base surface area B = 12.5663706 ft²
total surface area A = 89.0046189 ft²
In Terms of Pi π
volume V = 16 π ft³
lateral surface area L = 24.3310501 π ft²
base surface area B = 4 π ft²
total surface area A = 28.3310501 π ft²
