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 diameter of a circle with a radius of 12 inches?

2r = dIf you calculate the formula correctly, the diameter would be 24 inches.


How do you calculate radius when the have no radius and no diameter?

You use the information that you do have, and a formula that relates it to theradius or diameter of the circle. As an example: The circumference is very helpfulif you know it.


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 circumference of a round tank?

To calculate the circumference of a round tank, use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius of the tank. Alternatively, if you know the diameter ( d ), you can use the formula ( C = \pi d ). Make sure to use the value of ( \pi ) (approximately 3.14 or 22/7) to get the circumference in the desired units.

How do you calculate angular resolution?

Angular resolution can be calculated by dividing the wavelength of light by the diameter of the aperture. The formula is: Angular resolution = 1.22 x (wavelength of light / diameter of aperture). This formula gives the smallest resolvable angle that can be distinguished between two closely spaced objects.

Why you use newtons ring to determine wavelength?

Newton's rings can be used to determine the wavelength of light because the diameter of the rings varies with the wavelength of the light being used. By measuring the diameter of the rings, the wavelength of the light can be calculated using the formula for constructive interference.


If this wave travels at 16 cms it's wavelenght would be?

To calculate the wavelength, you can use the formula: wavelength = speed of wave / frequency. However, to calculate the wavelength, we need to know the frequency of the wave in addition to the speed. If you provide the frequency of the wave, we can calculate the wavelength.
