Answer:
Step-by-step explanation:
This might be easier to do in decimals. Let's try it.
3/5 = 0.6
1/10 = 0.1
rate = holes / hours
rate = 0.6/0.1
rate = 6 holes per hour
Try it with fractions.
rate = Invert and multiply the 1/10
rate = = 30/5 = 6
It's the same answer. Pick the method that you feel most comfortable with.
see screenshot
general formula is
r² = (x - x-center)² + (y - y-center)²
note that I choose a radius of 6 arbitrarily. you didn't provide the information about the radius, but just put in yours
