Kylee brought three circular rugs to put bedroom. Each rug has 6ft. Radius . What is the area of her that will be covered by all 3 rugs ? Leave answer is term of pi

Answer:

No, she cannot use a ratio of 21 to 6. You can figure this out in a few different ways. First you can simplify down the fraction 18/3, to get 6/1. 6/1 does not equal 21/6, because 21/6 equals 7/2. However, 6/1 it does equal 36/6. You could also noticed that three doubles to make six, yet 18 does not double to make 21. :D

Step-by-step explanation:

When an equation of circle is expressed in the form:

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

(h, k) is the center and r is the radius.

The center = the coordinate you have plotted on the graph.

Radius = how many units long the circle extends to.

SO, let's plug this in.

Coordinate plotted = (0, -4)

0 = h

-4 = k

(x - {0})^2 + (y - {-4})^2 = 2^2

(x - 0)^2 + (y + 4)^2 = 4

(whenever we have two negative signs next to each other, it turns the digit to the right of the final negative sign positive.)

Now we are left with this final equation as a solution:

x^2 + (y + 4)^2 = 4.

I hope this helped~!

The standard form of a circle:

- the coordinates of a center of a circle

- the radius

We have:

the center:

the radius:
