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 = Ïr².
Substitute the radius value into the formula: A = Ï * 40²
Calculating the area: A = Ï * 1600 = 5024Ï
When the value of Ï is approximated to 3.1416 and the multiplication is performed, the area is approximately 15,795.504.
Therefore, the correct answer is option 2) 5024Ï.
