How to calculate the diameter of a circle when the circumference of the circle is 7?
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
What is the outside diameter formula?
The formula to calculate the outside diameter of a circle is: outside diameter = diameter + (2 * thickness). This formula takes into account the thickness of the circle's material when calculating the overall dimension.
What is the mathematical formula for finding the radius of a circle?
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
If a circle has a diameter of 8 cm then what is the circumference of the circle?
A simple formula to calculate the circumference of a circle: so in this case:
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).
How do you calculate the circumference of a circle if you know the diameter?
Multiply the diameter by Pi as the formula Pi x d = Circumference. Where d stands for diameter.
What is the diameter of a circle with a radius of 12 inches?
2r = dIf you calculate the formula correctly, the diameter would be 24 inches.
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
How do find the circumference of a circle?
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
If I have a length of Eighty meters when formed into a circle what is its diameter?
The circumference of a circle is defined as 2(pi)d. Transpose the formula and calculate it.
What is the formula for calculate the diamerer of a circle?
The diameter of a circle can be calculated using the formula ( D = 2r ), where ( D ) is the diameter and ( r ) is the radius of the circle. Alternatively, if you know the circumference ( C ), you can use the formula ( D = \frac{C}{\pi} ), where ( \pi ) is approximately 3.14159. Thus, the diameter is twice the radius or the circumference divided by pi.
What is the formula for the diameter of a circle?
The diameter of a circle is twice its radius, or 2r.
