Answer:
D) 100,000 cubic feet
Step-by-step explanation:
The circumference of a circle is calculated as:
circumference = 2*π*r
Replacing with data and solving for r (radius of the silo):
125.7 = 2*π*r
r = 125.7/(2*π)
r = 20 ft
The volume of a cylindrical silo is:
volume = π*r²*h + 2*r³*π/3
where h refers to silo's high. Replacing with data and solving:
volume = π*20²*70 + 2*20³*π/3
volume = 104,719.755 ft³ ≈ 100,000 cubic feet
