<u>Answer:</u>
The height of the model is 2 feet 10.5 inches.
<u>Step-by-step explanation:</u>
<u>Given:</u>
scale of 1/3 inch=2ft
actual tower is 207 feet
<u>To Find:</u>
The height of the model = ?
<u>Solution</u>:
We know that 1 feet is 12 inches
Then 2 feet is = 24 inches
24 inches= of a inch.
The tower is 72 times the scale of the model.
Now the actual tower is 207 feet
=
, units feet
=>
=> 2 feet 10.5 inches.
Answer:
4in = r
Step-by-step explanation:
Different problem if the x was a variable in the question
formula for area of circle = pi x r^2.
So if the area of a circle is 16 pi in^2, it would be an obvious estimate that the radius is the square root of 16 which is 4 inches.
If the x was a variable, you would find the square root of 16x which is which would make it 4
as the radius.
