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.

Area of a circle = pi*radius2

πr2

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...

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

Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)

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.

Radius = +sqrt(Area/pi)

S = (pi) * (radius)2

The circumference of a circle with a radius of 5 centimeters 157.0796...The area of a circle with a radius of a 5 centimeters is 78.5398...

Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared

Area = pi R2

To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.

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

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).

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

Area of a circle = pi*radius2[π r2]

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.

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.

the radius is from the center of the circle to the edge so that's how you find the radius.

Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
