Answer:
302
Step-by-step explanation:
The answer would be 24pi inches.
You can find this by using the formula for a circumference and plugging in the value of the radius.
C = 2pi*r
C = 2pi * 12
C = 24pi
Given:
a.) The scale of the model is 1 in equals 47 ft.
b.) Danielle constructs a scale model of a building with a rectangular base her model is 2 inches in length and 1 inch in width.
To be able to determine the actual area of the base, let's first identify the actual dimensions of the base.
We get,


Let's now solve for the area of the base, since it is a rectangle, we will be using the formula below:

We get,



Therefore, the actual area of the base is 4,418 ft.².
If we have two similar triangles:
Triangle 1 (base 1 , height1).
Triangle 2 (base 2, height 2)
Then:
base 1 /height 1=base 2 /height 2
Data:
base 1=0.2 m
height 1= 1 m
base 2= 8 m
height 2=x
We calculate the height of the tower:
base 1 /height 1=base 2 /height 2
0.2 m / 1m=8 m / x
x=(8 m * 1 m) / 0.2 m
x=8 m²/0.2 m
x=40 m
Answer. the heigth of the tower will 40 m
1 switch sides
(x-4)=0
add four to both sides
x-4+4 = 0+4
simplify
x = 4
