What is the Area of a Circular Petri Dish with a Radius of 40?

Calculation of the Area of the Circular Petri Dish

Given: Radius of the circular petri dish = 40

To find the area of the circular petri dish, we use the formula for the area of a circle: A = πr².

Substitute the radius value into the formula: A = π * 40²

Calculating the area: A = π * 1600 = 5024π

When the value of π is approximated to 3.1416 and the multiplication is performed, the area is approximately 15,795.504.

Therefore, the correct answer is option 2) 5024π.
