A pizza has a diameter of 12 inches. Each piece has a central angle of radians. What is
Firlakuza [10]

Answer:

The area of one slice of pizza is 18 in²

Step-by-step explanation:

First we have to know that the 360 ​​° representing the circle expressed in radians are expressed as 2π

Now we must calculate the area of ​​the circle

a = π * r²

a = π * (12in)²

a = 144π in²

Now that we have the area of ​​the circumference we multiply it by (π/4) / (2π)

144π in² * (π/4) / (2π) =

144 in² * 1/8 =

18 in²

The area of one slice of pizza is 18 in²

What is the mean, median, mode, and range of the numbers 8,15,3,6,13,9
ivolga24 [154]

Hello There!

To find the mean, add up all the numbers and divide according to how many numbers there are. The mean for this set would be <em>"9"</em>

<em></em>

To find the median, place the numbers in value order and find the middle. if there is no middle, add up the two numbers in middle and divide by 2. In this set, the median would be <em>"8.5"</em>

<em></em>

To find the mode or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode. In this set, there would be no mode.

The range of a set of data is the difference between the highest and lowest values in the set. In this set, the range would be <em>"12"</em>
