This Grade 9 mathematics worksheet focuses on finding the volume of cylinders. Students identify whether a marked segment represents a radius or diameter, recall the cylinder-volume formula V = πr²h, convert diameter to radius, and solve multiple-choice volume problems using given measurements. Several items require rounding, including directions to round to the nearest tenth or hundredth and to use π = 3.14. With 10 multiple-choice questions, the worksheet gives students a focused opportunity to connect circle measurements to three-dimensional volume calculations. It is suitable for guided practice, independent review, or a quick formative check after instruction on cylinder volume. This free printable worksheet includes a complete answer key, helping teachers review choices efficiently and identify whether errors come from selecting the wrong radius or diameter, using an incorrect formula, or rounding inaccurately.

This Grade 9 worksheet uses 10 multiple-choice questions to build cylinder-volume skills. Students distinguish radius from diameter, find a radius from a diameter, select V = πr²h, calculate cylinder volumes, and round answers as directed, including work with π = 3.14.
Use the opening radius-and-diameter items to review which measurement belongs in the formula and how diameter relates to radius. Then have students identify V = πr²h before solving the cylinder-volume questions, and ask them to explain when a result should be rounded to the nearest tenth or hundredth.
Watch for students using the diameter directly in r² instead of first dividing it by 2, or choosing a distractor based on an incorrect cylinder formula. In the calculation items, check whether students substitute measurements consistently, use the instructed value of π, and follow the requested rounding place.
