Times length times width
Pi in math is use to find the circumference or area of a circle.
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
Find the diameter, then multiply that by Pi (about 3.1416). The result is the circle's circumference.
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.
The circumference is: 32.1
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
Area = (circumference squared)/(4 pi)
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
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.
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.
Area of the circle = (circumference)2 / (4 pi)Area = 0.0796 circumference2(rounded)
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
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
