What is the area of a circle with radius 10? (Use π ≈ 3.14)

To find the area of a circle, the formula used is A = πr², where A represents the area and r represents the radius of the circle. Given that the radius is 10, you would first square the radius to get 10², which equals 100.

Next, you multiply this square by π, using the approximation of π as 3.14. Therefore, the calculation becomes:

A = 3.14 × 100 = 314.0.

This calculation leads directly to the area of the circle being 314.0 square units. The option reflecting this calculation is indeed the correct answer. Understanding how to apply the formula for the area of a circle, along with the given value of π, is crucial in arriving at the right answer.
