A cylindrical rod is measured to have a length of 12.34 m and a diameter of 0.567 m. What is the volume of the cylinder to the correct number of significant figures? Use π = 3.14.
A
12 m³
B
13 m³
C
123 m³
D
1 m³
Correct Answer
Option B
Detailed Explanation
The volume of a cylinder is given by V = πr²h. The least number of significant figures in the measurements is 3 (for diameter), so the volume should be rounded to 3 significant figures.
