Answer:
The radius of the silo is 5.788 feet.
Step-by-step explanation:
Since the silo has the shape of a cylinder, then;
Volume of the silo = Volume of a cylinder = h
Where: r is the radius of the silo, and h is the height.
Given that: volume = 2106 cubic feet, and height = 20 feet.
Then,
2106 = x
x 20
2106 =
2106 x 7 = 440
14742 = 440
=
= 33.5045
⇒ r =
= 5.78831
r = 5.788 feet
The radius of the silo is 5.788 feet.
