Pi Day is celebrated on 14th March around the world and Calderhead High School enjoyed some fun ‘pi’ activities.
Pi (Greek letter “π”) is the symbol used in mathematics to represent the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. The BBC produced a great guide to pi (t.co/wvwpvzl4vP).
