Practice Questions
Question 1
Which instrument is commonly used to measure the diameter of a tree at breast height (DBH)?
Question 2

Question 5
A forester measures a tree's DBH as 30 cm and its height as 20 m. If the tree is approximated as a cylinder for a rough volume estimate, what is its approximate volume in cubic meters? Use the formula $V = \pi r^2 h$, where $r$ is the radius and $h$ is the height.
