Answer:
When the diameter is given you just take half of it so simply put what is half of 16pi and it will give your answer. :)
Step-by-step explanation:
The circle has a diameter of 16.
The formula for the circumference of a circle is diameter*pi
So, the circumference is 16*pi, or 16pi. (answer choice C.)

Answer:
x = -1/2.
Step-by-step explanation:
x^2 - 4 = (x - 2)(x + 2) so if we multiply each term by x^2 -4 we get:
2 - 1(x - 2) = 3(x + 2)
2 - x + 2 = 3x + 6
2 + 2 - 6 = 3x + x
4x = -2
x = -1/2.
