How do you find the circumference if you have the area of a circle?
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
How do you find the area of a circle with just the radis?
If you have the radius of the circle then just plug it into the equation which ispi x r2This equation is used to find the area of a circleSo if your radius is 5 then all you do is 52 and then multiply by piHope that helps.Jamz159
What equation can be used to find the area in square inches of a circle with a radius of 8 inches?
Area of the circle in square inches = pi*82
How do you solve circle area of 24centemeter?
You cannot SOLVE a circle. You can find the radius of a circle, or its diameter, or circumference or area. Or you can find the equation of a circle in the Cartesian system or in polar coordinates. Or find other characteristics of the circle. In any case, a circle cannot have an area of 24 centemeter. Apart from the fact that there is no such word - try centimetre (or centimeter). A centimetre is a measure of length, not area.
How do you find the radius of a circle using an equation?
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi

Area of the circle in square inches = pi*82
How do you find the radius of circle with area 144pi?
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

What is the approximate area of a circle with a radius of 3 feet?
Area of a circle equals pi (~3.14) multiplied by the radius squared. So to find the area of that circle your equation is (3.14)(3)^2 which equals approximately 27.
How do you find the area inside a circle?
use the equation Area=pi*r2 r is the radius of a circle If you are presented with the diameter of the circle, divide by 2 to receive the radius. Now, square and multiply by pi.
What is the radius of a circle with an area of 84.64 m2?
The area formula for a circle is...A= pi x r2Put your value for the area into this equation to find the radius.84.64m2 = 3.14159 x r226.94177152m2 = r2r = 5.19meters
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
