Laura works in the quality assurance department of a cpmpact dist (CD) manufacturing company. if the cd is 120 mm in diameter and the hole is 17 mm, how far from the edge of the cd should the edge of the hole be located?
these are the dimensions we're given |dw:1398449910117:dw|
we are interested in the distance from edge to edge. so we should measure the length from the center: |dw:1398449965913:dw|
The radius is a measurement of length from the center of a circle to its circumference. Also, radius = diameter/2 So, the inner circle has a radius of r=d/2, r=17mm/2
Then the radius (r=d/2) of the CD is r_cd = 120mm/2. The distance from the center of the CD to the outer edge is 60 mm, and the distance from the center to the end of the edge of the hole is 8.5 mm
