the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
Answer:
step 2; a negative times a negative = a positive.
Step-by-step explanation:
-4(6-b)=4
<u>-24 </u><u>+</u><u>4b=4</u>
4b=28
b=7
<em>*Remember that y and f(x) are the same.</em>
With f(2), you are solving for the output (y), given that the input (x) is equal to 2.
With f(x) = 2, you are solving for the input (x), given that the output (y) is equal to 2.
D I think so, I might be wrong tho
