Did you know?
WebThe ratio of the length (circumference) of a circle, C to its diameter m is π (a Greek letter spelled pi and pronounced "pie" in English-speaking countries). The decimal representation of π continues forever without repeating after the decimal point: π = 3.14159265... So if C / m = π, then C = m ⋅ π. Share Cite Follow answered Apr 1, 2016 at 21:58 WebTask 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. …
WebMultiply Pi (3.1416) with the square of the radius (r). Area = 3.1416 x r squared The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Example: The area of a circle with a radius (r) of 3 inches is: Circle Area = 3.1416 x 3 squared WebThe 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. This tells us that the circumference …
