  1. What is the area of a circle with a diameter of 10 m? (Use π ≈ 3.14)

    Answer: 78.5 m²

    Radius = 5 m, so area = πr² = 3.14 × 25 = 78.5 m².

  2. Two angles of a triangle measure 50° and 60°. What is the third angle?

    Answer: 70°

    The angles of a triangle sum to 180°, so 180° − 50° − 60° = 70°.

  3. A cylinder has a radius of 3 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)

    Answer: 282.6 cm³

    Volume = πr²h = 3.14 × 9 × 10 = 282.6 cm³.

  4. Convert 2,000 grams to kilograms.

    Answer: 2 kg

    There are 1,000 grams in a kilogram, so 2,000 ÷ 1,000 = 2 kg.

  5. A right triangle has legs of 6 and 8. What is the length of the hypotenuse?

    Answer: 10

    √(6² + 8²) = √100 = 10.

  6. What is the perimeter of a rectangle that is 9 in long and 4 in wide?

    Answer: 26 in

    Perimeter = 2(length + width) = 2(9 + 4) = 26 in.

  7. A pair of supplementary angles includes one angle of 120°. What is the other angle?

    Answer: 60°

    Supplementary angles sum to 180°, so 180° − 120° = 60°.
