s2008m [1.1K]

Answer:

k = 3

Step-by-step explanation:

Given that y and x are directly related then the equation relating them is

y = kx ←  k is the constant of variation

To find k use the condition y = 81 when x = 27

k = \frac{y}{x} = \frac{81}{27} = 3

A grain silo is in the shape of a cylinder with a hemisphere top. They cylinder is 20 feet tall. The volume of the silo is 2106
andreyandreev [35.5K]

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 = \pir^{2}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 = \frac{22}{7} x r^{2} x 20

2106 = \frac{440}{7}r^{2}

2106 x 7 = 440r^{2}

14742 = 440r^{2}

r^{2} = \frac{14742}{440}

r^{2} = 33.5045

⇒ r = \sqrt{33.5045}

     = 5.78831

r = 5.788 feet

The radius of the silo is 5.788 feet.
