To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
Is there supposed to me a picture or what?

Step-by-step explanation:
The formula to find the area of a circle: 
, where 
is the radius.
The formula to find the circumference (perimeter) of a circle: 
, where is the radius.
1) To find the circumference of the circle, we need to find the radius () first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the 
by bringing it to the other side.
÷
2) Find the circumference of the circle by using the formula, .
= 
= in
