PLEASE HELP
Write the equation of the circle graphed below.

Step-by-step explanation:

The standard form of a circle is

where h and k are the coordinates of the center and r is the radius.  The grids on our graph are 1/4 of a unit apart, and that will be important when we need to find the radius of the circle in just a minute.  But first the center.

The center is situated at (-2, -2).  That is our h and k.

The radius goes from -1.25 to -2, so the radius is .75 units long (or 3/4 of a unit).

Putting all of this together:

which simplifies to

i think it is 70

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
