Question

If an irrigation arm acts as the radius of an irrigation circle, how much land does it cover when the arm is 330 ft long? a) 330 square feet b) 330 cubic feet c) 330 acres d) 330 square miles

Answer 1

Explanation:

To calculate the land area covered by an irrigation arm acting as the radius of an irrigation circle, you can use the formula for the area of a circle:

Area = π * (radius)^2

In this case, the radius is 330 feet, so:

Area = π * (330 feet)^2

Area ≈ 108,900 square feet

So, the land covered by the irrigation arm when it's 330 feet long is approximately 108,900 square feet.

The closest answer choice is a) 330 square feet, but the correct answer is not exactly 330 square feet.
