Webπ. Draw a circle with a diameter (all the way across the circle) of 1. Then the circumference (all the way around the circle) is 3.14159265... a number known as Pi. Pi (pronounced like "pie") is often written using the greek … WebThis is because a fraction is the number of shaded parts divided by the number of equal parts. Let's look at some more examples. Example 9: In example 9, the circle has been shaded horizontally; whereas, in example 10, the circle was shaded vertically. The circles in both examples represent the same fraction, one-half.

WebFeb 14, 2024 · The area of a sector with a central angle α = 90° of a circle with radius r = 1 is π/4. To calculate this result, you can use the following formula: A = r² · α/2, substituting: r = 1; and. α = 90° · π/180° = π/2. … WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd.
