The given below is the mid sphere radius of octahedron formula to calculate the mid-radius of an octahedron on your own. Mid sphere radius can be calculated with the known value of edge length. From the formula, just divide the edge length by the integer 2 to get the mid-radius. You can refer the octahedron diagram to know which is the edge length. The range of output you get through the formula will be based on the unit of input you use for calculation.
Also, you can refer the online tool which is developed based on the mid sphere radius of octahedron formula to perform calculations with ease and get reliable results within the fractions of seconds.
