What area of lawn receives water from a sprinkler that sprays over 24 feet while rotating through an angle of 150 degrees?

To find the area of the lawn that receives water from the sprinkler, we need to consider the sector formed by the sprinkler’s spray. The formula for the area of a sector is:

Area = (θ/360) × π × r²

where θ is the angle in degrees, and r is the radius (distance the water sprays).

In this case, the radius (r) is 24 feet, and the angle (θ) is 150 degrees.

Plugging in these values:

Area = (150/360) × π × (24)²

Calculating this step by step:

1. First, we calculate (24)² = 576.

2. Then, substituting back into the formula:

Area = (150/360) × π × 576

3. Simplifying (150/360) gives us 5/12.

Therefore, Area = (5/12) × π × 576.

4. Now, multiplying this out, we get: Area ≈ (5/12) × 3.14 × 576 = (5 × 3.14 × 576) / 12.

5. This approximates to Area ≈ 754.67 square feet.

Thus, the area of the lawn that receives water from the sprinkler is approximately 754.67 square feet.
