Hi there!
The formula for the circumference of a circle is C = pi x D or C = 2 x pi x r. This means that the circumference is equal to either pi times the diameter or twice the radius.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Anita's speed rounded to the nearest hundredth is 0.28. The first 7 in the number 0.277 is the hundredths place. You look at the second 7 and you can see that 7 is greater than 5. So the answer is 0.28.

Answer:
(-2,8)
Step-by-step explanation:
To solve by substitution, first isolate a variable in one of the equations. Then, substitute the value of the variable from that equation into the other equation, giving either the x or y value of the solution. Finally, substitute that answer back into one of the two equations, finding the other missing value.
1) For both of the equations, the variable y has already been solved for. So, we can choose to substitute whatever y equals in one equation for the y in the other equation. Any choice is fine - I chose to substitute -4x for the y in y = 3x + 14.
2) Now that x has been solved for, substitute the value for the x in one of the equations. Any choice is fine here, too - I chose to substitute -2 in y = -4x:
3) Both the x and y value of the solution has been solved for. x = -2 and y = 8. Therefore, the solution is (-2,8).
For 2) and 4), check the picture below
that's the "secant segments from external point" theorem... and that's just an example... so... use that for those
now, for the other two, you'd want to post them separately, one at a time, easier to track and revise
