you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
The area of a circle that has a circumference of 16pi is: 201.1 units2
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
you use pi to calculate the area or circumference of a circle
Using the Circumference And Area.
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
There's no such thing as the "area of a circumference", no matter how you spell it.A circumference is a length, representing the distance around a circle, and doesn'thave an area.If you know the circumference of a circle, and you call it 'C', then the area of the circle isC2 / (4 pi)
Because of the radius of the circle
r, for radius
Well, what you do is you would find the circumference, or the distance around the circle.
Well, you can't really "convert" it, but I assumeyou want to calculate the circumference from the area. First, you need to know what figure you are talking about. For the specific case of a circle, I suggest you use the formula for the area of a circle, replace the known area, and solve for the radius. Once you have that, it is easy to calculate the circumference.
