14 A grain silo is shaped like a cylinder. The height of the silo is 60 feet tall, and the circumference of the base is a 20tt feet. Which measurement is closest to the volume of the silo in cubic feet?
F 3,769.9 ft
G 75,398.2 ft
H 226,194.7 ft 3
3 18,849.6 ft

Step-by-step explanation:

Given

Required

Determine the volume

First, we need to determine the radius of the base using:

Substitute 20 for C

Solve for r

 -- approximated.

The volume is then calculated as thus:

None of the given options is close to the volume of the silo

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
