You need to find the area of a circular base.
   The formula for area of a circle is pi x r^2.
Just plug in the information that you are given.
   A=3.14 x 1.5^2
Solve.
   A=7.065
Round to the nearest tenth.
   7.1 ft^2 of turf need to be painted for one base.

One of the world's largest stained glass windows is at kennedy International Airport in New York. It is a rectangle with a height to length ratio of 2 to 25. If the window is 24 feet high how long is it?

We have: 2/25= 24/?

Cross multiply:
2*?= 25*24
⇒ 2*?= 600
⇒ ?= 600/2
⇒ ?= 300

The length of the window is 300 ft~

Round 70.59 to nearest whole number

The nearest whole number simply means the number directly before the decimal. In this case, 5 is to the right of the decimal, so you round up. So the answer would be 71. Do you get it?

The Johnson's living room rug is 3 sq units wide and 4 sq units long. What is the area of the rug?

Well, the easiest way to do this is simply by using the formula. The area of a rectangle is given by the formula 
AREA= LENGTHXWIDTH
    The reason why i'm using the formula for the area of a rectangle is because a room is usually the shape of a rectangle. Anyway;
The length is 4
The width is 3
  So that is basically
AREA=4 x 3
AREA= 12. 
  So the area is 12n² 
  Hope i helped. Have a nice day

A candy bar box is in the shape of a triangular prism the volume of the box is 2400 cubic centimeters part A: what is the height of the box show your work.

The volume of a triangular prism is the "area of a triangle" times the "thickness."
The area of a triangle is (base times height) over 2.
V = ((b*h)/2)*T
Given V = 2400 cu. cm, b = 16 cm, T = 20 cm, and h is unknown,
h = (2V)/(bL) = (2*2400)/(16*20) = 15 cm

Note that the given 17 cm in the picture is useless.

Find the circumference of the circle. Round your answer to the nearest hundredth in the center of the circle is 4.5 ft. a 14.14 b 15.90 c 16.82 d 17.43

Answer:

a. 14.14 ft²

Step-by-step explanation:

The measurement given refers to the diameter of the circle. The formula for the circumference and area uses the radius of a circle, therefore it is always safer to use radius instead of diameter

The radius is half of the diameter, which is 2.25 ft.

A=2*r*\pi \\A=2*2.25*\pi \\A=14.14ft^{2}

Suppose you have a coupon for a 20% discount. You buy a game that costs $38. The sales tax rate is 5.5%. Sales tax applies to the cost after the discount. What is the total cost of the game?

$32.072 ≈ $32.07
20% of $38 is equal to $7.60
$38 - $7.60 = $30.40
5.5% of $30.40 = 1.672
$30.40 + $1.672 = $32.072

What is the perimeter of a square whose diagonal is 3 radical 2

Use trigonometry to get the side of the square. The diagonal of a square creates two right triangles. These right triangles are consistent - meaning their angles have 90, 45 and 45 degrees.
Getting the length of the side can either be used a cosine or sine function, that is
cos 45 = (3 radical 2)/x
x = (3 radical 2)/cos 45
x = 6

The perimeter of the square is 4*sides. Therefore,
P = 4*6 = 24 cm

The base and the height of a parallelogram are 18cm and 8cm.If both the base and height of the parallelogram are decreased by 50%, what is the area of the parallelogram?

If the base is decreased by 50%, it becomes 9. We get this by simply multiply 18 * 0.5
If the height is decreased by 50%, it becomes 4. Again, we just do 8 * 0.5
The area of a parallelogram is base * height.
9 * 4 = 36

NEED HELP QUICK!!! Nicole works at the corporate headquarters for a major organization. Some days she feels as if she spends all day in the elevator. Her office is on the middle floor. After working in her office for a couple of hours, she went up eight floors to meet with the human resource department to discuss her new promotion. She left that meeting and went up five floors to meet with stockholders. Following that meeting she went down nine floors for a reception in the private cafeteria. After that event, she went up seven floors to meet with her new boss. Finally, she went down thirty-two floors to the main entrance of the building, which is on the first floor, and out to meet a friend for dinner. How many floors does the building have? PLEASE ANSWER WITH EXPLANATION PLEASE, THANK YOU


The travels you have described are:

                                       (Middle floor) + 8 + 5 - 9 + 7 - 32

                                   =  (middle floor)  + 20 - 41

                                   =  (middle floor)  -  21  brought her to floor #1.

So                                   Middle floor  -  21  =  1

Add 21 to each side:    Middle floor  =  22 

The building has (2 x middle floor)  =  44 floors.
