To find the circumference of a circle you use the formula, C=2*pi*radius or C=pi*diameter, in his case you would use the first option, C=2*pi*radius, because the radius is the given value. You then plug the values into the equation to solve for the circumference...
C=2*pi*15
C=30*pi
C=30pi or approximately 94.2478
Answer:
the 3rd one! :))
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
Well, the closest number for 17 is 20, and for 27 is 30.
When we multiply those two numbers :
20*30=600
We got 600
1. Closed
2. IDK
3. No, because the first inequality says x is lesser than 5 but the second one says x is greater. X can't be both greater and lesser at the same time.
4. X>12
5. X

6. y<-8
7. 2.3 + w>18
8. -4t

9. b - 4.2 < -7.5
10. 2x

11. 4 + 8

- Correct
12. 5(-5) > -15 = -25 > -15 = Incorrect
The answer is the first one
