Answer:
9,114.81 ft³
Explanation:
The solid is composed of a cylinder and a hemisphere
Volume of the solid = volume of the cylinder + volume of the hemisphere
= πr²h + ⅔πr³
Where,
r = 8 ft
h = 40 ft
Plug in the values into the equation
Thus:
Volume of the solid = π*8²*40 + ⅔*π*8³
= 8,042.4772 + 1,072.33029
= 9,114.80729
= 9,114.81 ft³ (nearest hundredth)
