Best Answer

Area = π*r2

radius = √(area/π)

[the square root of (area divided by π)]

you have to do the division first before you take the square root of that result

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

Radius = +sqrt(Area/pi)

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

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.

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

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)

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.

Area of a circle = 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).
