Answer:
The circumference is 18.84 inches.
Step-by-step explanation:
To find the circumference of the circle we can use the formula:

Where C is circumference and r is radius.
Now that we have the formula, we can substitute the numbers:

it would be 0, because in the origin equations, the d's cancel out since it's x-x, only 2 would be left, therefore the correct answer is A since 0+2=2
Answer: the answer is c^2 / 10
Hope this helps :p
Step-by-step explanation:
Answer:
Infinite number of solutions.
Step-by-step explanation:
Are the equations written correctly? They are identical. Since they overlap, every point is a solution for as long as the lines reach. Since no one is stopping them, the answers are infinite.
