A bird seed feeder has the approximate shape of a cone with a diameter of 12 centimeters and a height of 25.5 centimeters. What
timurjin [86]
The equation for the volume of a cone is: 
V= \frac{1}{3}  \pi r^{2} h
where V = volume of the cone, r = radius of the circular base, and h = height of the cone.

You are told that the height, h = 25.5 cm. You are also told that the diameter is <span>12 centimeters. Remember that the diameter of a circle is just twice the radius. Divide 12 by 2 to get the radius: r =12/2 = 6 cm.

Since you know </span>h = 25.5 cm and r = 6 cm, plug these values into your equation for volume of a cone and solve for V, volume:
V= \frac{1}{3} \pi r^{2} h\\&#10;V= \frac{1}{3} \pi (6) ^{2} (25.5)\\&#10;V \approx 961.33

Answer: B) <span>961.33 cm³ </span>

On a quiz show, Linda won $10 less than three times as much as Charlie. If Linda won $800, how much did Charlie win?
PilotLPTM [1.2K]

Using a system of equations, it is found that Charlie won $270.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount earned by Linda.
  • Variable y: Amount earned by Charlie.

Linda won $10 less than three times as much as Charlie, hence:

x = 3y - 10

Linda won $800, hence the amount won by Charlie is found as follows:

800 = 3y - 10

3y = 810

y = 810/3

y = 270
