Question 11821: I am not sure were this question belongs but I need an algebraic expression that give the area of a circle witha circumfernce c. Here is the kicker I can't have any equal signs (=) or have diameter (d) in any part of the answer.
The only hint I have to go off of is Hint: The circumference of a circle with radius r is 2*pi*r, and its area is pi*r^2.

and

You want a formula for the Area in terms of the Circumference C.

So, solve for r in the first equation, by dividing both sides by .

Substitute this into the second formula, and you will have:

Divide out the factor

I suppose without any equal signs the final answer is this:

R^2 at SCC

Ok, since you have been asked for an "expression", there wouldn'tbe any = signs any because "expressions" don't have = signs.
Let's write an expression for the area of a circle:
But you need it in terms of c, the circumference.
Let's write an equation for c:
Now, solve this for :
and, after squaring, substitute this into the expression for the area:
Now simplify:
This is an expression for the area of a circle in terms of the circumference, c.
