Answer:
B). 37.68 feet.
Step-by-step explanation:
Circumference = diameter * π
= 12 * π
= 37.68 feet.
Answer:
45
Step-by-step explanation:
When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
If the diameter is 16, then the radius is 8.
Your equation is:
(x - 7)² + (y + 5)² = 64
It’s C becuase when you divide the 700$ by 200$, you will get 3.5. So you basically multiply it with 60$ and there you have your answer which is 60*3 + 60*0.5=210
