Answer:
D
Step-by-step explanation:
I am confused but thats my guess
The correct answer is
Slope intercept form: y = mx + b
m=6
b=-15
Intercepts:
x-intercept=2.5
y-intercept=-15
So the formula for a circle is Pie * r^2
If you divide 300 by pie and then Square root it you would get your radius
And once you have the radius you would use the equation of 2pie * r to find the circumfrence.
Answer is 61.38
Hope this helps!
