To find the area of a circle with a diameter of 14, first calculate the radius: radius = diameter / 2 = 7. Next, use the formula Area = π * radius^2. So, the area is π * 7^2 = 49π ≈ 153.94 square units.
FAQs & Answers
- How do you find the area of a circle? To find the area of a circle, use the formula Area = π * radius^2. First, determine the radius by dividing the diameter by 2.
- What is the relationship between diameter and radius? The radius of a circle is half of its diameter. So, if you know the diameter, you can find the radius by dividing by 2.
- What is the numerical value of π? The numerical value of π (pi) is approximately 3.14159. In calculations, it is often rounded to 3.14 or used symbolically as π.
- Can you give an example of calculating the area of a circle? Sure! For a circle with a diameter of 14, the radius is 7. The area is calculated as π * 7^2, which equals 49π, approximately 153.94 square units.
