STUDENTS at South Craven School enjoyed a day of celebrating the famous mathematical constant known as Pi.

The ratio of a circle's circumference to its diameter, usually approximated as 3.14159 and represented by the Greek letter "π", was chosen as the theme for activities for maths pupils at the school last month.

A spokesman for South Craven said: "March 14, unsurprisingly, is officially deemed to be Pi Day as it is the third month and the 14th day.

"This year was even more special as the date was 3/14/15, the same as the approximate Pi figure of 3.1415.

"As it was also Comic Relief day and non-uniform day that Friday, our maths teachers decided to explore the fun possibilities of the subject of Pi with their classes.

"During the lessons, the students learned how to discover the meaning of π for themselves, looked for hidden pi in crop circles and, best of all, ate pie!"
