Choose the correct formula to find the diameter of a job (D) is in mm if the cutting speed (v) is in m/min and the revolution per minute (N) is given.
1
\(D = \frac{{1000 \times v}}{{\pi \times N}}\)
2
\(D = \frac{{\pi \times N}}{{1000 \times v}}\)
3
\(D = \frac{{1000 \times \pi }}{{v \times N}}\)
4
\(D = \frac{{1000 \times N}}{{\pi \times v}}\)
