Use the formula area = pi x radius2. If you replace everything you know, you can solve for the radius.

How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
How do you find the area of a circle by only knowing the 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.
What is the required piece of information tho find the area of a 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).
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the radius of a circle when given only the area?
Area = pi*radius2 So, radius = sqrt(area/pi)
Find diameter when you only have area of a circle?
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
What is the area of a circle with a radius of 3 in by 4 in?
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
How do you find a area with the diameter of a circle?
Area = Pi(radius)squared. You only need the radius of a circle to find the area. To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii. After you have found the radius, plug in the radius into the area equation: Area = Pi(radius)squared In other words, you can say the other equation for the area of a circle is: Area = Pi(1/2Diameter)squared
How do you work out the area of a circle with only the diameter?
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
How do you find the area of a circle only knowing the radius?
If you know the radius (say it's 4), square the radius and multiply that number by pi. So for a radius of four, it would be 4 X 4 = 16 X 3.14 = 50.24, the area of the circle.
How to find a sector area in a circle if you have only the arc length?
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
Does the area of a circle depend on the radius?
Yes. To get the area, you take the radius, square it, and multiply that by Pi, so it is the only variable and does affect the circle's area.
