What is the cubic root of pi?

What is the volume of a cylinder in milliliters if the height is 16 cenimeters and the radius is 4 centimeters?
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)
A circular tank is 12m in diameter and 7.5 m in height how much water does it hold when half full?
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.
What is the square root of pi multiplied by 64?
sqrt(pi)*64 = 113.437 (approx)
Volume of cylindrical solid?
πr2h or the radius squared multiplied by pi multiplied by the vertical height of the cylinder.
