How do you calculate each side of a square when there is 9 circles with an area of 314 each?

I'm assuming you mean the following:
--------
|OOO|
|OOO|
|OOO|
--------
Where:
- Each circle touches, but does not overlap, each adjacent circle
- There is no gap between the edge of the circles and the edge of the square
- The area of each circle is 314 units2
Let r be the radius of a circle
The area of a circle is pi x r2
r = square root of (314 / pi)
r = approx*. 10 units
The length of each side of the square = 6 x r = approx*. 60 units
* approximate, because the value of pi is not exactly 3.14

How do you calculate area in math?
Squares: Take two sides and multiply them against each other, ex. 3.5•3.5= the area. Rectangles: Same as squares. A square is a rectangle. Circles: Radius times radius times pi equals area.
What is the area between four circles with a radius of 10?
This is assuming that the four circles are arranged in a square, with each circle touching two other circles at their tangents.First, you need to determine the area created by drawing a square between the center points of all of the circles.Circle radius = 10Side of square = 10 * 2, or 20Area of square = 20 * 20, or 400Now that you have that area, you can deduct the four quarters of the circles inside the square area. You can do it the long way, but four quarters of identical circles equals the area of one of the circlesArea of circle = pi * r^2= pi * 100=3.14159 *100=314.159Square Area - (4) quarter circle area400 - 314.159= 85.841
How do you calculate the area of a 94 inch square?
If each side is 94 inches then its area is 94 times 94 = 8836 square inches
Four circular flower beds each with a radius of 10 meters the way they're arranged forms a space between them i need to know the area in meters squared of the section of one flower bed and the space?
Imagine 4 circles just touching, like this OO .............................................................. OO only closer. Draw a square connecting the centres of the 4 circles. Given the circles each have a radius of 10 metres the length of each side of the square is (10+10) =20 metres and the area of the square is 400 square metres. The area of each quarter of the circle that is within the square is one quarter of pi times r squared so the four quarters = 100pi square metres so the space between the circles is the difference.
How do you calculate the surface of a wedge?
split the wedge into a triangle and a and rectangle or square. Then calculate the surface area for each shape and add them together
How do you calculate the square meters area of an oddly shaped area?
Geometric configurations that do not conform to standardized shapes (squares, triangles, circles, etc.) can still have their areas determined. They can be calculated by dividing the given parcel into known shapes (and thus formulae) and then calculating the areas of each, and combining their values.
The formula A equals 6s square will calculate the surface area of a cube Suppose you have a cube that has a surface area of 216 in square what is the length of each side?
216 square inch total surface area, divide that by 6 to have the area of each square face, 36 square inch. The square root of that is the length of one side, 6 inches.
Could you Calculate the length of each side of a square room if the area is 169 M2?
You find the square root 0f 169 which is 13.
What is the area of a figure formed using a square with sides of twelve kilometers and three circles with diameters of twelve kilometers each?
area of square 144 sq km, area of a circle 12 x pi so area of three circles 36 x pi. Taking pi as 22/7 gives 113 and one-seventh sq km as total area of circles so grand total is 257 and one-seventh sq km
How do you calculate the square footage of an oddly shaped area?
Divide your oddly shaped room into smaller standard shapes. Calculate each smaller shape's area then add all of your answers together.
How do i calculate how much wallpaper to purchase for my bedroom?
Multiply the length of each wall by the height of each wall and that will give you the area of the walls. Combine the resulting numbers for each wall and you have the area in square feet.
How many square feet is a room 10 x 15?
The floor and the ceiling each have an area of 150 square feet. We can't calculate the area of the walls without knowing the height of the room.
