ATLANTA - After six weeks of learning, a 7 1/2-year-old Decatur girl showed off her math skills on National Pi Day.

Channel 2 Action News ran into the girl named Madison at the Atlanta Science Festival Tuesday evening.

Pi is the ratio used to compute the circumference, area and volume of circles — which is 3.14159 plus.

The number goes on infinitely. Madison can name up to 62 digits: 3.1415926535897932384626433832795028841971693993751058209749445

National Pi Day is actually a U.S. holiday, declared in 2009.

Pi Day also is Albert Einstein's birthday. The German theoretical physicist was born on March 14, 1879.

According to the Pi Day website www.piday.org, "Pi has been calculated to over 1 trillion digits beyond its decimal point."
