Y=3/4x+1/4 if you take a close look at where the line crosses over the y-axis.
D), I believe it is -42. Correct me if im wrong :}
I believe B . Because it seems equivalent
Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows.
Area=πr^2
Thus;
64=πr^2
64/π=r^2
r^2=20.3718
r=sqrt(20.3718)
r=4.5135
Therefore the length of radius,r=4.5135 units
