A farmer plans to build the small silo shown to store chicken feed. What is the circumference of the base of the silo if it can
mamaluj [8]

Answer:

  4√(3π) ft ≈ 12.28 ft

Step-by-step explanation:

The formulas for volume of a cone and a cylinder can be used to find the radius of the silo. Then the formula for the circumference of a circle can be used to find the circumference.

__

Relevant formulas are ...

  • V = πr²h . . . . . volume, cylinder with radius r, height h
  • V = 1/3πr²h . . . . volume, cone with radius r, height h
  • C = 2πr . . . . . . . . circumference of a circle with radius r

__

<h3>radius from volume</h3>

The total volume of the silo is the sum of the volumes of a cylinder of height (15 -6) = 9 ft, and a cone of height 6 ft. Both have the same radius: r. The total volume is given as 132 ft³.

  V = πr²h + 1/3πr²h' . . . . . . h = cylinder height, h' = cone height

  132 ft³ =  πr²(9 ft +1/3(6 ft)) = πr²(11 ft)

  r² = 132 ft³/(11π ft) = 12/π ft²

  r = √(12/π) ft = 2√(3/π) ft

<h3>circumference from radius</h3>

Then the circumference of the silo is ...

  C = 2πr = 2π(2√(3/π)) ft = 4√(3π) ft ≈ 12.28 ft

The circumference of the base of the silo is 4√(3π), about 12.28 feet.

We have to find the probability N(11,2)>12, wherein N(11,2)
is the normal law with mean 11 and standard deviation 2. 
Using a scientific calculator we get the probability 0.3. 

Now multiply by the population which is 1000 like this:
0.3*1000=300.

There is 300 <span>spiders  in the colony which weigh more than 12 grams</span>
