Is pi greater than 3?

• Yes

• No

Is the decimal value in pi never ending?

Example: never ending 2.02927271892... ending 1.097

• No

• Yes

Does pi’s decimal number have patterns?

Example: pattern 2.132132132... no pattern 5.9270112726433...

• Yes, it does have patterns

• No, it does not have patterns

Example: You walk around a circle which has a diameter of 100 m, how far have you walked around the circle?

• 314m (to the nearest m)

• 100m

• 3.141592...m

• 708m

We can use pi to find a Circumference when we know the Diameter,

What does that mean?

• Circumference = pi x Diameter

• Radius = 3 + pi

• Pi = pi x 1

• Diameter = 1/4 x pi

How can pi also be written down?

• It could be written as π

• There’s no more ways it could be written down

Can you use the Nilakantha series to find pi

Nilakantha series: 3 + 4/2×3×4 − 4/4×5×6 + 4/6×7×8 − 4/8×9×10 + ...

• Yes

• No
