# What is pi used for

Pi is useful for all kinds of calculations involving the volume and surface area of spheres, as well as for determining the rotations of circular objects such as wheels. That's why pi is important for scientists who work with planetary bodies and the spacecraft that visit them Pi is used to calculate how far the rover should travel with each wheel rotation. By measuring the distance from one wheel mark to another, rover drivers can determine if the wheels are slipping or if they've driven the expected distance. › Use pi like a Mars rover driver to solve this puzzler! 13

If you bought a pulse oximeter to use at home, a device designed to measure the amount of saturated oxygen in the blood, you might have come across the term normal PI. PI stands for perfusion index, and it is an indication of the strength of your pulse, but there is more to it than that Pi is most commonly used in certain computations regarding circles. Pi not only relates circumference and diameter. Amazingly, it also connects the diameter or radius of a circle with the area of..

Perfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site. The PI's values range from 0.02% for very weak pulse to 20% for extremely strong pulse. The perfusion index varies depending on patients. Pi is an irrational number engineers use in many everyday tasks, including calibrating the speedometer of automobiles. The wheels on a vehicle are circular, so the circumference of the tire, which is the distance it travels each rotation, is equal to pi times the diameter Using pi, it can measure things like ocean wave, light waves, sound waves, river bends, radioactive particle distribution and probability like the distribution of pennies, the grid of nails and mountains by using a series of circles. Some examples of daily uses of Pi: 1) Electrical engineers used pi to solve problems for electrical application
