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.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
