pi*radius2 = area
radius = square root of (area/pi)
circumference = 2*pi*radius

Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
How do you calculate the area of a curcumfrence?
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)
Why is Pi used to calculate circumference and area of circles?
Because of the radius of the circle
What variable would you use to calculate the area or circumference of a circle?
r, for radius
IF the circumference of a circle is 6.28 what is the area?
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.
How do you calculate circumference and area of pi?
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
How do you calculate the area of a circle if you know the circumference?
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2

How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.
How do you covert area into circumference?
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.
If the circumference of a circle is increased by 50 then the area will be increased by?
there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.
