SIZIF [17.4K]

Answer:

The land that is covered with an irrigation arm of 370 ft is $430,084\ ft^2$

Step-by-step explanation:

<u>Area of the circle</u>

Being r the radius of a circle, its area can be calculated as follows:

$A=\pi\cdot r^2$

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:

$A=\pi\cdot 370^2$

$A=430,084\ ft^2$

The land that is covered with an irrigation arm of 370 ft is $430,084\ ft^2$
