How do you find the diameter of a circle if they give you the area?
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
What is the formula for finding the circumference of a circle when you have the area?
The formula for the area of a circle is given by pi times radius times radius.The formula for circumference of a circle is 2 times pi times radius.As area is known, the radius is easy to work out, like thisFrom Area = pi X r X rthenradius = (square root of (area/ pi))From circumference = 2 X pi X radiusthenCircumference = 2 X pi X (square root of (area/pi))This can be simplified toCircumference = 2 sqrt(pi X area)You will remember that pi stands for an endless decimal ratio that starts 3.142...A:Divide the area by pi.Get the square root of the answer. That's the radius.Double it. That's the diameter.Multiply the diameter by pi. That's the circumference.
What is the square root of 8 in radical form?
To get the square root of 8, you have to multiply the root of 2 and the root of 4. The root of 4 then simplifies to 2, so the square root of 8 equals 2 times the square root of 2.
What is the square root of 200 in radical form?
10 times square root of 2 The square root of 200 is sq. root of 100 times 2, then the sq. root of 100 is 10 and remains the sq. root of 2. check the answer: square root of 2 is 1.41, 10 times 1.41 is 14.1 196 is closed enough to 200 and the square root of 196 is 14.
A square is inscribed in a circle of area 18 PI find a side of a square?
Area of circle: 18pi Radius of circle: square root of 18 = 3 times square root of 2 Using Pythagoras' theorem each side of the square is 6 units in length
