To start, we recognize that the circumference of a circle divided by its diameter (or twice the radius) is approximately 3.14, a ratio denoted as pi (π). With this information, we can write the formula for a circle's circumference: C=2πr. To determine a circle's area, we can star...
What is pi used for? In basic mathematics, pi is used to find the area and circumference of a circle. Pi can be used to find an area by multiplying the radius of the circle squared times pi. So, to find the area of a circle with a radius of 3 centimeters, the calculation would ...
The Basics of Signal to Noise Ratio Calculations In simpler terms, Signal-to-Noise Ratio (SNR) is the measure of the difference between the strength of the desired signal and the background noise. The noise floor, defined as the ambient transmissions from other devices or unintentional interferen...
This is a snapshot of the key information from the ratio table above. We have the quantities in the question (160 is 100%) and the quantity we need to find (120%). We can also see the single percentage multiplier for the calculation – the strategy that is considered the ‘endgame’ ...
