Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is the circumference of a circle with an area of 314 in2?
Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
How do I use pie in geometry?
A pie chart is used to compare facts with each other visually in the form of a circle whereas pi is used for example in finding the area of a circle.
When you use 3.14 for pie in math do you multiply or divide?
That depends on the given problem but if its for finding the circumference or area of a circle then 3.14 is multiplied appropriately.
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
What is the pie sign use for?
The sign pie is used for finding the area in a circle.
What is the circumference of a circle with an area of 314 in2?
Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
What is the mathematical formula for finding the radius of a circle?
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
What measurement to find how much frosting covers the top of a birthday cake area circumference or perimeter?
Circumference is what you use when finding the area of a circle.
How do you find the area of a circle that has a radius of 10?
Well, since the formula for the area of a circle is Pi (3.14) times the radius squared, you can use substitution to get an equation that looks like this: 3.14(102) ...which can be simplified to 3.14(100), which can be simplified to come up with the answer of 314 square units.
How do I use pie in geometry?
A pie chart is used to compare facts with each other visually in the form of a circle whereas pi is used for example in finding the area of a circle.
Why do you square the radius when finding the area of a circle?
Whether you are finding the area of a circle or the area of a square or any other geometrical shape, it is always the case that to go from a linear measurement (a radius, a side, or whatever) to a surface area requires you to use a square of the linear measurement; you are increasing size in two dimensions, length and width, and therefore the effect is the increase the area exponentially, not linearly.
When you use 3.14 for pie in math do you multiply or divide?
That depends on the given problem but if its for finding the circumference or area of a circle then 3.14 is multiplied appropriately.
Find the area of a circle with a radius of 8 meters to the nearest square meter Use 314 for?
There seems to be a typo in the problem you have...they are asking you to us 3.14 as pie or the symbol with 2 lines and a wavy line on top
Where and when can you use a pi in maths?
Finding are or circumference of a circle or cylinder.
