The formula for the area of a circle is A = π*r^2. This formula represents multiplying the radius of the circle squared by the number π (pi). This is because the area of a circle is equal to the radius multiplied by itself (squared) times pi. The other options are incorrect because they either involve dividing the radius by 2 (option C) or multiplying it by 2π (option D), which are not the correct methods for finding the area of a circle. Option A also does not account for the need to square the radius. Therefore, option B is the only correct choice.
