Answer:
592 hours
Step-by-step explanation:
Given


Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle

Let t represent the time take to cover 11000m²;
The relationship between these parameters is:

Substitute 3.14 for π

Divide both sides by 3.14



Take square root of both sides



Divide both sides by 0.10




<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
Step-by-step explanation:
Case 1 :


Case 2 :


it is a polygon and it would be a decagon since there are 10 sides
Hi there! The fourth answer is correct.
In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.
Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:

Filling in this formula, brings us to the following answer.
