The formula to calculate split times is given by percent of time= (2-4*phi)* (percent of distance) ^2 + ((4*phi)-1) *percent of distance). Positive splits and negative splits are the two types of splits.
velocity times gravity times friction:)
pi times r squared
the formula for area of a square is length times width
You have to multiply the base times the height and then divide that by 2.
not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.
If you are trying to find the volume of something, remember there is a formula which is volume = length times width times high.
you find the formula... then you calculate it. Its that simple.
To calculate volume of water for hydro test you need to use the formula pi times radius (squared) times length. Pi is equal to 3.14.
A round swimming pool is a right circular cylinder, so you can use the formula pi times the radius squared times the height to calculate the volume.
SA equals pi times the radius squared
pi x R squared times height where R = radius
Perimeter is the sum of its 4 sides Area is its length times its perpendicular height
