Answer256pi
Step-by-step explanation:
Area=pi*r^2
=pi*16^2
256pi
Point slope formula y-y1=x(x-x1)
In this problem, you have to find the y- intercept of

. I graphed mine into a graphing calculator. An algebraic way to find it is to input x=0 in the function. The y-intercept is 5. You can see the y-intercept for the new one is -2. That means we shifted the graph down 7 units. (Vertical Shift down 7)
k=-7
I believe it would be - 0.8. Hope it helps! :)
