The Greek letter π ("pi") represents the ratio of the circumference of a circle to its diameter. In Excel, π is represented in a formula with the PI function, which returns the number 3.14159265358979, accurate to 15 digits:
WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. http://www.areacircle.com/
WebFinding the Circumference and Area of a Circle Step 1: Read the given word problem and identify the radius {eq}(r) {/eq} or diameter{eq}(d) {/eq} of the circle. 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.
WebTherefore, the circumference circle equation is C = 2 πr. Example 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference.
