Answer:
C. 56.25π
Step-by-step explanation:
Circumference=15π=πd⇒d=15
Area=πr^2⇒r=d/2⇒r=7.5⇒π7.5^2=56.25π
Slope-intercept form is , where is the slope and is the y-intercept.
, so change the equation to represent this.
Great! Now the function is in slope-intercept form, so we can just see that , or the slope, is equal to
I think it is B
