Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area.

There is a window in the middle of the wall, so he'll only need to paint the shaded part shown. How many square feet is just the window? [Note: The wall and window are both rectangular.]

For this case what is asked is to find the area of the window.
 The area of the window in this case is a rectangle.
 Therefore, the area is given by:
 A = (18 * (1/12)) * (2)
 A = 3 feet ^ 2
 Answer:
 
the window is:
 
A = 3 feet ^ 2

Answer:

The answer would be 3ft.

Step-by-step explanation:

The area of the whole thing is 48ft. To find the area of the window, we have to multiply the base of the window by the height of the window. We have to put 18in. into feet. 18in. = 1.5ft. Multiply 1.5 x 2 and you get 3ft.

Hope this helps. :')

The diameter of a circle has endpoints A(1, 3) and B(4, 7), what is the
lana [24]

Answer:

The circumference of the circle is 5π

Step-by-step explanation:

First we need to calculate the diameter  

for this we have to know the distance between A(1, 3) and B(4, 7)

X =  Xb - Xa

X = 4 - 1

X = 3

Y = Yb - Ya

Y = 7 - 3

Y = 4

b - a = (3 , 4)

now that we have the distance of x and r we can calculate its distance using Pythagoras

h = hypotenuse

x = leg 1 = 3

y = leg 2 = 4

h² = x² + y²

we replace the known values

h² = (3)² + (4)²

h² = 9 + 16

h² = 25

h = √25

h = 5

The diameter of the circle is 5

Now we need to calculate the circumferencefor this we need to use the circumferenc formula of a circle:

c = circumference

d = diameter = 5

π = pi

c = π * d

we replace with the known values

c = 5  * π

c = 5π

The circumference of the circle is 5π
