Answer :
Final answer:
The question seems to ask for the perimeter of a circular object using the area provided, but it incorrectly requests a negative value. Perimeter is always positive, and the missing information about the circular object prevents a correct calculation.
Explanation:
The student appears to be asking for the perimeter of a circle or a similar circular object, given information about the area of the circle. However, there is a discrepancy as the question asks for a negative value for the perimeter, which is not possible. Perimeter, being a measure of distance around an object, is always a positive value. Furthermore, the question suggests using an approximate value of 3.14 for pi (π). The provided information includes an area A = 4.5 m², which is calculated using the formula A = πr², where r is the radius of the circle. To find the perimeter (circumference) of a circle, the formula C = 2πr is used. With r being derived from the area, we could calculate the perimeter accordingly.
However, since the information provided contains unrelated data such as dimensions of other objects and characteristics of lenses, and since there is no actual description of an 'object above', we are unable to proceed with the calculation as the radius of the object in question is not specifically given. We would calculate the perimeter using the derived radius from the given area if the information were complete and coherent.
