Final answer:
The question appears to involve solving for a variable related to the area of a circular ring, which normally would use the area formula A = πr². However, with insufficient information provided, especially regarding the variable p, a specific solution cannot be given.
Step-by-step explanation:
The task at hand involves solving for the variable p given the area A of a circular ring, which seems to be a variation of the circle's area formula A = πr².
However, without a clear definition of p in the context of the circular ring or further details, we cannot proceed with a specific solution.
It's important to note that when dealing with circular shapes, the area is given by the formula A = πr², where π is Pi (approximately 3.14159), and r is the radius of the circle. Therefore, the problem may involve the internal and external radius of the ring to find p, which we do not have.
With the given example of A = πr² = (3.1415927...)×(1.2 m)² = 4.5238934 m² but then limiting the answer to two significant figures due to the precision of the radius, we get A=4.5 m².
