How to calculate area in a circle?
Depends on what you know. Like if you know the radius, square it and multiply it by pi. If you know the diameter, do the same thing as you do with the radius except do it after finding half of that diameter.
What is the radius for a circle?
To know what a radius is you have to kno what a diameter is. The diameter is the distance accross a circle through its center. The radius is half the diameter.
How do you get the diameter of a circle?
That depends on what you know. If you know the radius of the circle, double it to get the diameter. If you know the circumference of the circle, divide it by π to get the diameter. If you know the area of the circle, find its square root and divide the result by π to get the radius then multiply by 2 to get the diameter.
Define radius of a circle?
In order to fully understand what the radius of a given circle is, you must know the diameter. The diameter is the distance across the circle through the center. The radius of a circle is half the diameter. For example, if the diameter of a circle is 8 inches, then the radius would be 4 inches.
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
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
