Area of a circle
Circumference of the circle
Let us re-write the equation of area of circle:
Multiplying and dividing with 2:
Hence, <em>A</em> in terms of <em>C</em> can be represented as:
Step-by-step explanation:
check it.. i have solved it for you.
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to 
.
Remember that an equation
represents a line with slope 
and y-intercept 
. Since both equations given have a slope of -2, but have different y-intercepts, they are parallel.
Remember that an equation
