PLEASE HELP<br>Write the equation of the circle graphed below.

klasskru [66]

Answer:

Step-by-step explanation:

The standard form of a circle is

$(x-h)^2+(y-k)^2=r^2$ 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:

$(x-(-2))^2+(y-(-2))^2=(.75)^2$ which simplifies to

$(x+2)^2+(y+2)^2=\frac{9}{16}$

butalik [34]

Answer:

134

Step-by-step explanation:

first, separate the floor into 3 different rectagles to calculate the area and then add them together.

area of rec=L*B

rec 1: 9.5*7=66.5

rec 2: (10.5-4.5)*(14.5-5-7)=15

rec 3:5*10.5=52.5

Then:

66.5+52.5+15=134
