The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Area = 201 m2
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
Well, what you do is you would find the circumference, or the distance around the circle.
In a circle, the area of the circle is pi times the radius squared
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
The answer depends on what information you are given.
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
Area of a circle = pi*radius2
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
