Formula for the volume of a cone = 1/3 * 3.14 * r^2 * h Therefore, volume = 1/3 * 3.14 * (2)^2 * 3 = 12.57m^3 .
If you have a surd, for example root27, in order to simplify it you need to find factors of it which are square numbers. Multiplying surds is like regular multiplication, for example, root27 = roo...
