Circles and pi
Web2. Since the exact value of pi can never be calculated, we can never find the accurate area or circumference of a circle. 3. March 14 or 3/14 is celebrated as pi day because 3.14 are the first digits of pi. Math nerds around the world love celebrating this infinitely long, never-ending number. 4. WebCIRCUMFERENCE and AREA of CIRCLES The definition of pi gives us a way to calculate circumference. The circumference of a circle is the distance around a circle. If π = , then C = πd. You can also calculate the …

WebMar 15, 2024 · Circumference is the distance around the circle (its perimeter), and area is the space inside the circle. C = π*D or C = 2*π*r. A = π*r². The two options for the circumference equation are, in fact, equivalent, since D = 2r. You may be wondering why mathematicians split the 2 and the r around the π, instead of just saying π2r.
