Some farmers use a circular irrigation method. An irrigation arm acts as the radius of an irrigation circle. How much land is co
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

Why is division by zero not allowed? Explain using your knowledge of how division is related to subtraction.
vivado [14]

Division by zero is an operation for which you cannot find an answer, so it is disallowed. You can understand why if you think about how division and multiplication are related. But no value would work for x because 0 times any number is 0. So division by zero doesn't work.
