Answer:
The volume of grain silo is 116.5 m³
C is correct.
Step-by-step explanation:
Given: Garin silo form by cylinder and hemi-sphere. Diameter = 4.4
Radius = 4.4/2 = 2.2 m
Cylinder:
Height of cylinder (h) = 6.2 m
Radius of cylinder (r) = 2.2 m
Hemi-Sphere:
Radius of Hemi-sphere (r) = 2.2 m
Volume of Grain Silo = Volume of Hemi-sphere + Volume of Cylinder
Volume of Silo [tex]=\dfrac{2}{3}\pi\cdot 2.2^3+\pi \cdot 2.2^2\cdot 6.2[/tex]
Volume of Grain silo = 116.5 m³
Hence, The volume of grain silo is 116.5 m³
