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.
The formula is 2pie(radius).
radius = 1/2 diameter
3.14 times the radius times 2
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
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.
The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432
radius = diameter/2
radius = diameter/2.
The centrifugal speed can be calculated using the formula v = rω, where v is the speed, r is the radius, and ω is the angular velocity. This formula relates the linear speed of an object moving in a circle to its distance from the center and how fast it's spinning.
The formula is 2pie(radius).
The formula that relates wavelength (λ) and period (T) for a wave is: λ = v * T, where v is the speed of the wave.
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
It is: 2*pi*radius
Well to find the radius it is diameter/2.
Diameter = 2*Radius
Radius, "R" = D/2 where D=Diameter.
