2 because in the equation of a circle it is x^2 + y^2 = r^2, r=radius so you would take the square root of 4, leaving the radius of the circle to be 2.
That would be the hundred thosand place
Answer:
It is 2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
To start off, you know 18 hours= 720
So you could automatically get rid of B and D since 19 and 17 are not 18.
After that, you have it down to A and C. The way you would find how much she charges for one hour is dividing 720 by 18. When you do that it means you are divding 720$ into 18 different groups each group representing an hour. When you divide 720 by 18 you should get 40. So every hour she makes 40 dollars. 40x 2 hours is 80. I hope I helped you!
