Answer:
h = 3/A
Step-by-step explanation:
A = 3h
Divide both sides by 3 to isolate h:
A/3 = 3h/3
Simplify and get
A/3 = h or h = A/3

Answer:
The land that is covered with an irrigation arm of 370 ft is 
Step-by-step explanation:
<u>Area of the circle</u>
Being r the radius of a circle, its area can be calculated as follows:

The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:


The land that is covered with an irrigation arm of 370 ft is 
2 3/10 = 2.3
To get this number as a percent, we need to multiply it by 100: 2.3 is a whole number, and can be represented by fraction 2.3/1
A percentage is represented by a fraction over 100. So to transform 2.3/1 to a percentage, just multiply both numerator and denominator by 100, and you'll get 230/100.
So 2 3/10 is 230% as a percent.
Hope this Helps! :)
