13 lut 2023 · The formula for calculating the area of a circle is A = π r 2 where pi (π) equals 3.14 and the radius ( r ) is half the diameter r = d /2. Determine the diameter of the circle. The first step for calculating the area of a circle from its diameter is to find that diameter.
In this class, you will learn the formula for Area of Circle (using Diameter), a detailed description about the inputs in the formula, and how to use this formula to find the Area of Circle for different sets of inputs. Area of Circle. The formula for Area of Circle \(( A )\) using diameter \((d)\) is: \( A = \) \( \frac{π d ^2}{4} \) where
Circle Worksheets. This generator makes worksheets for calculating the radius, diameter, circumference, or area of a circle, when one of those is given (either radius, diameter, circumference, or area is given). They can be made in PDF or html formats.
If you are given the diameter (which is twice the radius) then you would need to divide the diameter by 2 to get the radius and the use the formula A = πr 2. Example: Find the area of a circle with a diameter of 8 units. Use 3.14 for π. Divide the diameter by 2 to get the radius. Radius = 8 ÷ 2 = 4. A = πr 2 = (3.14) (4) 2 = 50.24 units 2.
How to use the formula to calculate the area of the circle given the radius or the diameter? Example: Find the area of a circle with radius 3cm. Find the area of a circle with diameter 20cm. Show Video Lesson
Understand that you can easily determine the area of a circle using the formula Area = π × r^2, where π is approximately 3.14, and r represents the radius of the circle. Note that radius is half the diameter of a circle.
