What is the formula liquid volume in cylinder?
Volume = 1/3 pr2 x height V= 1/3 pr2h Surface = pr2 + prs S = pr2 + prs =pr2 + pr
Finding the perimeter of an object?
It depends what geometric shape the object is.ShapesFormulaRectangle:Area = Length X WidthA = lwPerimeter = 2 X Lengths + 2 X WidthsP = 2l + 2wParallelogramArea = Base X Heighta = bhTriangleArea = 1/2 of the base X the heighta = 1/2 bhPerimeter = a + b + c(add the length of the three sides)TrapezoidPerimeter = area + b1 + b2 + cP = a + b1 + b2 + cCircle Try the Online tool.The distance around the circle is a circumference. The distance across the circle is the diameter (d). The radius (r) is the distance from the center to a point on the circle.

Log 2 plus log 4 equals log 2x?
log(2) + log(4) = log(2x)log(2 times 4) = log(2x)2 times 4 = 2 times 'x'x = 4

What is log base 5of 125?
log(5)125 = log(5) 5^(3) = 3log(5) 5 = 3 (1) = 3 Remember for any log base if the coefficient is the same as the base then the answer is '1' Hence log(10)10 = 1 log(a) a = 1 et.seq., You can convert the log base '5' , to log base '10' for ease of the calculator. Log(5)125 = log(10)125/log(10)5 Hence log(5)125 = log(10) 5^(3) / log(10)5 => log(5)125 = 3log(10)5 / log(10)5 Cancel down by 'log(10)5'. Hence log(5)125 = 3 NB one of the factors of 'log' is log(a) a^(n) The index number of 'n' can be moved to be a coefficient of the 'log'. Hence log(a) a^(n) = n*log(a)a Hope that helps!!!!!
