Question from sanjay, a student:

If I have a cylinder with 40mm diameter and I will cut it at an angle
20 degree so what would be the increased radius or dia.??? of the cylinder

Sanjay,

Is this what you mean?

cylinder

|CA| = 44 mm, Angle CAB measures 20 degrees and you want to find |AB|. What trig function relates |CA|, |AB| and the measure of the angle CAB? What is the length of AB?
