How many feet in a radian
WebDec 21, 2024 · Note that when an angle is described without a specific unit, it refers to radian measure. For example, an angle measure of 3 indicates 3 radians. In fact, radian measure can be considered dimensionless, since it is the quotient of a length (circumference) divided by a length (radius) and the length units cancel out. WebIt's also straightforward to find the area if you know the radius: a = \pi r^2 a = πr2 Using the Radius Calculator You can enter the radius and then compute diameter and circumference …
