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.

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.

In a circle, the area of the circle is pi times the radius squared

If the circumstance of a circle is 108pi then what is the radius of the circle

The only piece of information required to find the area of a circle is the radius of the circle. Once you know the radius of the circle, the area is simply the radius squared multiplied by pi (approximately 3.14).

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.

To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by 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...

To find the radius the formula is pi*radius*raduis So it is going to be 2 to the second power.......Leaving you with an answer of 4 inches......Be sure to include pi

The radius of a circle and the area of a circle are directly proportionate. This is because the area of a circle is calculated by the formula: Area = pi * radius2. Since we are using the radius to find the area, there is an association between the two.

The area of a circle is 153.86cm².find the radius of the circle

Area of a circle = pi times radius squaredDiameter of a circle = 2 times radius

radius = b/2*pi

Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded

Area of a circle = pi*radius2

By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2

If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)

you can find the circle's area by doing 3.14 multiplied by the circle's radius i hope that helps you thank you

You measure the radius of the circle and then square it and multiply by Pi.
