Approximate:
50.3 ft, 62.8 ft, 75.4 ft
Step-by-step explanation:
Let's find the radius of each silo using the given information.
<em>"The largest silo has a diameter of 24 feet."</em>
<em>"The radius of the smallest silo is one-third as big as the diameter of the largest."</em>
<em>"The middle-sized silo has a radius that is 2 feet greater than the radius of the smallest silo."</em>
The three radii are: 8 ft, 10 ft, and 12 ft.
Now we use the circumference formula with each radius to find the circumferences.
Smallest:
Middle:
Largest:
The circumferences above are exact. If you want approximations, then use a calculator and an approximation for pi.
The circumferences are approximately: 50.3 ft, 62.8 ft, 75.4 ft
