Question

What is the dimension of radius?

Answer 1

Answer:

A radial diameter dimension is a group design object. It allows for the dimensioning of an arc or circle with respect to the diameter, rather than the radius. The dimension can be placed either internally or externally, in relation to the circumference of the arc/circle.

Explanation:

Answer 2

Answer:

[2πr] =[2]•[π]•[r] =1•1•L =L since the constant's 2 and [ π] are the dimensionless and the radius r is a length . We see that 2πr has the dimension of length, which means it cannot possibly be an area.
