Answer:
Step-by-step explanation:
If y varies directly as x, then we can write the relation
where k is the constant of proportionality.
We substitute y=-319 when x=29.
This implies that:
The variation equation now becomes
Answer: the circles radius is 2
The equation for circumference of a circle is 2*pi*r
And the equation for the area of a circle is pi*r^2
The only way both of these equations can be true is if 2r(pi)=(pi)r^2
Or
2r=r^2
And when is the square of a number equal to two times the number? When the number is 2
So the radius must be 2
