the cylindrical part of an architectural column has a height of 325 cm and a diameter of 30cm. Find the volume of the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.

30/2 = 15cm = r
(Pi)r^2 = area of circle
(Pi)(15)^2 =706.5cm
Area of circle x height = volume
706.5 x 325 = 229613cm^3

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
