What is the formula to calculate circumference using radius?
Circumference = 2*pi*radius
How do you find the diameter without the circumference?
The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).
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.

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

If the circumference of a circle with a radius of 3.2 cm?
The circumference of a circle with a radius of 3.2 cm is approximately 20.1 cm. This can be calculated using the formula: circumference = 2 * π * radius.

How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
Why you are using pi to calculate circumference of the circle?
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
How do you get a circumference?
Using a compass and the circumference is measured by 2 times pi times radius or diameter times pi.
How do you work out the area of a circle using pi?
Pi, by itself is not enough. You need the radius which is the length from the centre of the circle to its circumference (its boundary). If the radius is r, then the area is pi*r*r If, instead of the radius, you have a diameter - the length from one side to the other, through the centre - then radius = diameter/2. Once you have r you can calculate the area. If you have the circumference, then that is 2*pi*r and from that you can determine r and so calculate the area.
