Answer:
Okay, here are the steps to find the volume of the cylindrical part of the column:
Height of cylinder = 305 cm
Diameter of cylinder = 30 cm
Circumference = pi * diameter = 3.14 * 30 cm = 94 cm
Radius = diameter / 2 = 30 / 2 = 15 cm
Volume of cylinder = pi * radius^2 * height
= 3.14 * (15 cm)^2 * 305 cm
= 4789 cm^3
So the answer is A: 4789 cm^3
