Formula for calculating the volume of a cylinder = pi*radius2*length giving your answer in cubic units. Therefore: pi*42*9 = 452.3893421 cubic units. To the nearest whole number: 452 cubic units.
27.8 IS given to the nearest tenth.
The answer depends on the values of the variables. Since these are not given there is no point in using a calculator.

If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
