**Idk**, Tuesday, February 3, 2015 at 5:05am15 mins means 90 degree.

This step is difficult for ones who are new or beginners kinda! =

If you draw the shape it becomes a sector. And to find the distance the TIP has travelled, you would have to use the ARC LENGTH FORMULA, which is

Arc length= Degree travelled➗360 ✖️2(pi) ✖️r

Use this formula and find the solution! Steps are as following:

Degree travelled is 90 degree

Pi is 22➗7

r is the radius or the length which is 6 inches

Now multiply pi with 2 then multiply it by radius which is six. Then multiply it by 90 and divide the final answer by 360. The answer you get is the distance travelled by the TIP.
