I saw in Google’s page this cute logo in commemoration of Pi Day.
I didn’t know there was such but now that I did, I checked some details.
Pi Day is celebrated on March 14 or 3.14 being the first three digit of the pi value (3.141592653589793238462643383279502884197…infinite series).
It also coincides with the birthday of Albert Einstein, a famous scientist and mathematician.
Pi is the ratio of the circumference of a circle to its diameter. The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter.
where c is circumference and d is diameter.
So when you order a 16 inches pizza it refers to the diameter. You might want to measure it's circumference by a tape measure but why bother? you can use the equation above and the answer is 50.24 inches (C = 3.14 x 16). Easy right?
Happy Pi Day everyone!
