The ratio of a model building's dimensions to the building's actual dimensions is 1/52. If the height of the model is 15 inches,

g100num [7]

Set this up as a proportion with the model stuff on top and actual building stuff on bottom. $\frac{1}{52} = \frac{15}{x}$ . Cross multiply to get x = 780. The actual building is 780 inches. In feet that is 65.

suppose the circumference of a crop circle is 150.7968 hectometers (hm) what's the radius of the circle? (usett=3.1416)

gulaghasi [49]

Answer:

The radius of the circle is $24\ hm$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have

$C=150.7968\ hm$

$\pi=3.1416$

substitute and solve for r

$150.7968=2(3.1416)r$

$r=150.7968/(2(3.1416))=24\ hm$
