If you have a list of numbers for which you want to find the average, Example: 3, 4, and 5 The first thing that you need to do is figure out how many numbers there are in the list: Example: 3 Then you need to find the sum of the numbers in the list: Example: 3 + 4 + 5 = 12 Then you divide the sum by the number of numbers in the list: Example: 12 / 3 = 4 And the result is the average of the numbers.
If the area is a square, 1/4 of the perimeter is the length of one side. That length squared is the area. The area will be the product of two numbers whose sum is half the perimeter.
There are many methods to do this. One is to calculate the are of the enitire figure. Then figure out the area of the smaller area. Then divide the smaller figure's area by the larger figure's area and change the answer to a percent. For example, if you were asked to figure out what percent of square A with sides measuring 5 cm was covered by square B (which is completely inside of square A) with sides of 1 cm. 1. Calculate the are of square A. 25 cm2 2. Calculate the are of square B. 1 cm2 3. Divide square B by square A. 1/25 or 0.04 4. Convert to a percent. 4%
4 and 12
You find the mean of negative numbers the same way you find the mean of any numbers. You add them up and then you divide by the number of numbers. An example, using -3, -4, -6, and -9. The sum is -22. N is 4. The mean is -5.5.
for area you times the two numbers and for perimeter you add the numbers
You add the numbers they give you and divide by the amount of numbers they give you. For example: Find the median of these numbers 20,30,40,50 Since there is 4 numbers add them up, and you get 140 So then do 140÷4=35
There are 24 different arrangements of 4 numbers (4 factorial or 4!). If you allow numbers to be repeated then the figure becomes 256 (44)
To find the area of a square you must times/multiply the numbers for 2 sides. Example: If you have a square that is 4 inches long and 4 inches wide, the area would be 16 inches.
If you have a list of numbers for which you want to find the average, Example: 3, 4, and 5 The first thing that you need to do is figure out how many numbers there are in the list: Example: 3 Then you need to find the sum of the numbers in the list: Example: 3 + 4 + 5 = 12 Then you divide the sum by the number of numbers in the list: Example: 12 / 3 = 4 And the result is the average of the numbers.
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
a five point star is made up of 10 or 4 triangles depending on how you look at it. if you can figure out the area of those triangles, you can figure out the area of the star, also known as a pentagram.
If the area is a square, 1/4 of the perimeter is the length of one side. That length squared is the area. The area will be the product of two numbers whose sum is half the perimeter.
None. These are numbers and numbers do not have surface areas.
494.5
In similar figures, any unit of area is proportional to the square of any linear measure. In this case, since the perimeter of the larger figure is twice as big, the area of the larger figure will be 4 times as big.
Surface area of a sphere = 4*pi*radius2 and measured in square units
