Read through the full deck, or practise recalling each answer above.

  1. What is the formula for the curved surface area of a cylinder?

    Show answer

    2πrh, where r is the radius and h is the height.

  2. What is the formula for the total surface area of a cylinder?

    Show answer

    2πr² + 2πrh, where r is the radius and h is the height. This includes both circular ends and the curved surface.

  3. How many circular faces does a cylinder have?

    Show answer

    Two circular faces — one at the top and one at the bottom.

  4. What is the area of one circular end of a cylinder with radius r?

    Show answer

    πr²

  5. When calculating the area of a label wrapped around a cylindrical can with overlap, what must be added to the curved surface area?

    Show answer

    The width of the overlap. For example, a 1cm overlap adds an extra strip of area equal to height × 1cm.

  6. When a cylinder is cut in half horizontally, which surfaces must be included in the surface area calculation of the remaining piece?

    Show answer

    The curved surface, the two circular ends (top and bottom), and the new rectangular cross-section created by the cut.

  7. If a cylinder has diameter 8m, what is its radius?

    Show answer

    4m. The radius is half the diameter.

  8. What does it mean to give an answer 'in terms of π'?

    Show answer

    Leave π as a symbol in the answer rather than calculating its decimal value. For example, 50π cm² rather than 157.08 cm².

  9. What dimensions are needed to calculate the surface area of a cylinder?

    Show answer

    The radius (r) and height (h) of the cylinder.
