The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
I can think of no context in which a cubic inch displacement has to be multiplied consistently by a quarter pi.I can think of no context in which a cubic inch displacement has to be multiplied consistently by a quarter pi.I can think of no context in which a cubic inch displacement has to be multiplied consistently by a quarter pi.I can think of no context in which a cubic inch displacement has to be multiplied consistently by a quarter pi.
1/3 multiplied by pi multiplied by radius squared multiplied by height
pi multiplied by r squared multiplied by height
pi multiplied by the radius squared
pi squared + 3.193029
Square root of Pi is about 1.772
The formula for finding the volume of a cylinder is pi multiplied by radius squared multiplied by the height. So for this case it would be pi multiplied by 6 squared multiplied by 7.5. But since you want it when it is HALF full, you would divide by two, so the answer would be 135 multiplied by pi, or around 424 metres squared of water.
πr2h or the radius squared multiplied by pi multiplied by the vertical height of the cylinder.
pi multiplied by the radius squared
sqrt(pi)*64 = 113.437 (approx)
square root of x/pi
1 Cubic Centimeter = 1 Milli-Liter or (1 cc = 1 ml) you have volume of a cylinder is (pi) * R * R * H (or pi R-squared H) Where pi is the constant = 3.141592654 ...etc R is the radius, in your case is 4.... R squared makes 16 then H is 16. 3.14159 * 16 * 16 = 804.2 cubic cenitmeters (because you have 3 dimensions of measurements in centimeters multiplied together, thus you now have cubic centimeters. just pi and R squared multiplied together would have been the area of a circle, and that would be 50.2 square centimeters)
If you take pi as 3.141592654, then the answer is 2.145029397 to 11 significant figures.
Imagine the end of the pipe as a circle. If r is radius then area is pi (r squared). So volume is, Pi multiplied by r squared and multiplied by the length. Make sure the radius and length are in the same units e.g. inches. so if 0.5 is diameter in inches then radius is half that 0.25. so r squared is 0.0625 inches2 length in inches is 12 x 250 i.e. 3000 inches. So answer is pi(3.14.......) x 0.0625 x 3000 = pi x 187.5 cubic inches. n.b. 1 cubic foot is 12 x12 x12 = 1728 cubic inches. if you want to convert to cubic feet.
π (pi). If you square pi and take the square root of that, you get pi. If you take the square root of pi and square that, you again get pi.The general answer to "What is the square root of x squared?", where x is any real number, is x itself -- but depending on where you put the implicit parentheses (whether you square first or take the square root first) the intermediate value may be an imaginary number.Pi cannot be represented by an exact decimal (because it cannot be represented by a fraction, which is what "irrational" means in mathematics), but the beginning is 3.141592653589793238462643383279502884197. For more digits and more info, see Wikipedia's article on "Pi" is useful.Edit:All true except for one minor point: The mathematical answer to "What is the square root of x squared?" is not x itself. It is +x OR -x. So, the square root of pi squared is + pi or -pi3.1415926535897932384626433
The same as the 8th decimal place of Pi itself.
The diameter squared multiplied by Pi/4 Area = Pi/4 x D2
For what it is worth, the answer is 4.818029 (to 6 dp)
because 1.7725 squared is 3.14 or 1.7725x1.7725=3.14
If you use pi as 3.14, the answer is 12.56. If you use the pi button on your calculator, it is still simplified to 12.56, but if you want the full number, it is 12.56637061. The algebra is pi multiplied by diameter OR pi multiplied by radius squared Pi is often just used as 3.14
