Paul bought a circular rug for his living room. The rug has a diameter of 11 feet. About how much of Paul's living room will be covered with the rug?Use 3.14 for pie

The rug has covered approximately 95 square feet of the living room.

Step-by-step explanation:

Given:

Diameter of rug = 11 feet

We need to find the area covered in living room by the rug.

Solution:

Diameter of rug = 11 feet

Radius is half of the diameter.

Radius of the rug =

Now it has been given that rug is in circular shape.

So we will find the area of the rug using Area of circle formula which is given by π times square of the radius.

Framing in equation form we get;

area of the rug =

Hence The rug has covered approximately 95 square feet of the living room.

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
