Question 1185372
<br>
It should be obvious that the suggested solution is not right.  It is nonsensical to say that an arc of a circle with diameter 10cm cut off by a central angle of 75 degrees has an arc length of 750cm...!<br>
The problem with the solution is as the other tutor points out -- the formula s=rt for arc length gives the arc length when the radius is r and the angle is t RADIANS -- not t degrees.<br>
