What is the area of a circle with radius 14? (Use π ≈ 3.14)

• A. 615.44
• B. 612.79
• C. 611.21
• D. 612.87

Answer: (A)

To find the area of a circle, the formula used is A = πr², where A represents the area, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle. In this case, the radius provided is 14. First, calculate the square of the radius: 14² = 196. Now, substitute this value into the area formula along with the approximation for π: A = 3.14 * 196. Performing the multiplication gives: A ≈ 3.14 * 196 = 615.44. Thus, the area of the circle with a radius of 14 is approximately 615.44. This confirms that the correct answer is indeed the first choice, as it accurately reflects the calculated area based on the given radius and the approximation of π.
