This free printable Grade 8 mathematics worksheet helps students calculate the volume of cylinders and cones using given dimensions. Across 11 multiple-choice questions, students identify whether a marked segment represents a radius or diameter, substitute measurements into volume calculations, interpret diagrams, round answers when needed, and apply the skill to a cone-shaped cup context. The worksheet supports focused practice with both cylinder and cone volume problems, including questions that require students to distinguish radius from diameter before calculating. It is useful for independent practice, guided review, homework, or a quick formative check after instruction. A complete answer key is included, and teachers can use the printable PDF or assign the digital version through Wayground.

This Grade 8 worksheet uses 11 multiple-choice questions to practise finding the volume of cylinders and cones, identifying whether a marked segment is a radius or diameter, and rounding volume answers when required. Students work with diagrams, numerical measurements, and a real-world cone-shaped cup problem, building accuracy in selecting the correct measurement and applying it to a volume calculation.
Begin by reviewing how a radius differs from a diameter, since several items ask students to identify the marked segment before calculating. Model one cylinder and one cone problem from the worksheet, emphasizing careful substitution of the given dimensions and appropriate rounding. Then have students solve the remaining multiple-choice items and explain why the selected option is reasonable, especially for the cup-volume question.
Watch for students treating a diameter as the radius without converting it, which can substantially change the calculated volume. Students may also choose a cylinder calculation when the figure is a cone, omit the cone’s one-third factor, or select an answer with incorrect rounding. The radius-versus-diameter identification items provide a quick way to spot the source of errors in the numerical questions.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for the 11 multiple-choice questions. For printable submissions, scan student work with the Wayground for Teachers app to streamline grading. The PDF option also supports schools that want to reduce screen time while retaining structured practice.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the diagrams, labels, and multiple-choice options are easier to follow. You can also enable a dyslexia-friendly font or translate the worksheet into another language. These file-level options can make the radius-and-diameter items and volume calculation prompts more accessible without changing the core practice.
