Question

Some farmers use a circular irrigation method. An irrigation arm acts as the radius of an irrigation circle. How much land is covered with an irrigation arm of 370 ft?
The land that is covered with an irrigation arm of 370 ft is

Answer 1

Answer:

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

Step-by-step explanation:

Area of the circle

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  $430,084\ ft^2$
