How is pi used in everyday life

Report as

Many many trades need to know the area or circumference of a circle, or a part of one.
- A landscaper or DoItYourself person needs to know the length of border and the area of garden tiles,
- the shire planner needs to check calculations by companies quoting on roads with "roundabouts",
- joggers like to be able to roughly know the distance around their small or large local ovals
- a pizza maker needs to be able to work out the saving in toppings if they vary how far from the edge they put it on
- a mass producer of round objects like plates or round furnishings has to know the area each item needs of ceramic or cloth
- then many people need to be able to work out volumes of cylinders even roughly eg water left in a round tank
- a car mechanic who changes the bore of a car's engine needs to recalulate the volume (cc or cubic inches0 of the motor
- then every machine or natural event that has a repetitive nature (engines, day length, car suspension and shockers, electric mortors ) has an equation that uses pi in trigonometry (sin cos and tan)

Tx people.
So if your local oval you jog around is 50 yards centre to edge
just double it
then times by pi (3.14)
and you know the circumference you are jogging
=314 yards..
