Q1Which statement correctly distinguishes a right circular cylinder from a slant cylinder?
In a right circular cylinder, the circular bases are parallel and the axis meets them at a right angle. Equal base circles and square-unit surface area are still important, but they do not by themselves state the right-cylinder condition.
Q2For each task, decide whether the measurement needed is surface area or volume. How many tasks need volume: filling water in a cylindrical bottle, painting the outside of a cuboid, packing grain in a cubical box, pasting paper on the curved side of a tin?
Volume is needed when a container is being filled or its capacity is being found, so water in a bottle and grain in a box count. Painting or pasting paper covers exposed surface, so those are surface-area tasks.
Q3A closed cuboid tank is 8 cm long, 5 cm broad and 4 cm high. What is its volume?
Volume measures the three-dimensional space occupied, so the cuboid volume is 8 × 5 × 4 = 160 cubic cm. The options in square cm confuse volume with surface area or area, while 17 cm is only a sum of lengths.
Q4Imran wants to put a rope around a rectangular garden. Which measurement is needed first?
The correct choice is perimeter. Imran is not covering the garden with grass or filling a tank; he is placing rope along the boundary, so the answer must be a linear unit.
Q5A rectangle is 9 cm by 4 cm. Which statements are true? I. Its area is 36 square cm. II. Its perimeter is 26 cm. III. The same number 36 must also be its perimeter.
Devika should choose C. The area is 36 square centimetres, but the perimeter is 2 times 13, or 26 centimetres. This question tests area-perimeter separation.
