5 dni temu · Formula to calculate the diameter of a circle given its radius, or vice versa. The formula of the diameter of a circle is the most straightforward of the equations and says that diameter ( d) equals twice the radius ( r): d = 2r. r = d/2. The calculation of circumference and area of a circle formulas are more tricky.
5 dni temu · If the radius is known: We can calculate the diameter by multiplying the radius by 2: d = r × 2. If the circumference is known: The diameter can also be calculated using the circumference: d = c / π. If the area is known: The formula to calculate the diameter from the area of a circle is: d = 2 × √(a / π)
5 dni temu · These are the formulas to calculate the circumference and area of a circle: c = 2πr A = πr² = πd²/4. where: c stands for circumference; r for radius; and; d for the diameter of the circle. π is a constant approximately equal to 3.14159265359 and, among other things, represents the circumference-to-diameter ratio of any circle.

1 dzień temu · In previous studies, the widely adopted approach for determining RL j radius is to make the RL j area equal to the urban area 46 or to employ a uniform RL j radius of 5 km or 10 km (refs. 47 , 48 ).
4 dni temu · A simple approximation formula is: \[ R_{min} = D + 2T \] where: \(R_{min}\) is the minimum bend radius (mm), \(D\) is the outer diameter of the tube (mm), \(T\) is the thickness of the tube wall (mm). Example Calculation. For a tube with an outer diameter of 25 mm and a wall thickness of 3 mm, the minimum bend radius would be:
4 dni temu · The formula to calculate the turning radius (\ (R\)) of a car is given by: \ [ R = \frac {L} {\sin (\theta)} \] where: \ (R\) is the turning radius in meters, \ (L\) is the wheelbase of the car (distance between the front and rear wheels) in meters, \ (\theta\) is the steering angle in degrees.
