Final answer:
The area of the circular petri dish with a radius of 40 is calculated using the formula A = πr², resulting in an area of 5024π, which is option 2).
Step-by-step explanation:
The question asks for the area of a circular petri dish with a given radius. To calculate the area of a circle, the formula A = πr² is used, where A is the area and r is the radius. The radius provided is 40, so we substitute this into the formula to get A = π * 40². This gives us the area as A = π * 1600, or 5024π when π is approximated to 3.1416 and the multiplication is carried out (5024π is approximately 15,795.504). Thus, between the given options, the correct answer is option 2) 5024π.
