Answer:
To answer the question, we need a radius or diameter. For know, I hope this equation helps.
Step-by-step explanation:
C=2π<em>r</em>
Circumference = 2 (pi) radius
For your problem, it says to use 3 for pi.
C=2(3)<em>r</em>
*If you have the diameter, but not the radius, divide that number by 2. Your radius is half the diameter.
You just need to divide to get to 1n. -3n = 84
So the answer is 84/ -3 = -28. n= -28
Write the equation of the circle with center (3, 2) and radius r = 7. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25
