While running for class president, Amanda handed out a campaign button. The catalog from which the button was ordered states that it has a circumference of 12.56 inches. What is the button's area?

A = 12.554 square inches

Step-by-step explanation:

Let's start with the formulas:  

Circumference = ; Area =

We can use the circumference to find the radius, r, which we need for the area

12.56 =

Isolating r gives us

A =

Solving gives us 12.554, which you can further round if necessary.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
