Correct Answer
Option D
Explanation
To determine why Option 4 is the correct answer, we need to calculate the original and new volumes of the cylinder and compare them. ### Original Volume Calculation: The formula for the volume of a right circular cylinder is given by: \[ V = \pi r^2 h \] where \( r \) is the base radius and \( h \) is the height. For the original cylinder: - Base radius,тАжRead More
