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
Using the Circumference And Area.
you use pi to calculate the area or circumference of a circle
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)
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
Because of the radius of the circle
r, for radius
To calculate the circumference of a circle from its area, first use the formula for the area ( A = \pi r^2 ). Given that the area is 8.2 cm², you can solve for the radius ( r ) by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). Once you find the radius, use the circumference formula ( C = 2\pi r ) to calculate the circumference.
Well, what you do is you would find the circumference, or the distance around the circle.
