  1. A circular garden has a diameter of 14 feet. What is the approximate area of the garden? (Use π ≈ 3.14)

    Answer: 153.86 sq ft

    Area = π × r² = 3.14 × 7² = 3.14 × 49 ≈ 153.86 square feet.

  2. Two angles are supplementary. One angle measures 73°. What is the measure of the other angle?

    Answer: 107°

    Supplementary angles sum to 180°, so 180° − 73° = 107°.

  3. A rectangular box has a length of 10 cm, width of 4 cm, and height of 5 cm. What is its volume?

    Answer: 200 cm³

    Volume = length × width × height = 10 × 4 × 5 = 200 cm³.

  4. On a coordinate plane, what is the distance between points (1, 2) and (4, 6)?

    Answer: 5

    Distance = √[(4−1)² + (6−2)²] = √[9 + 16] = √25 = 5.

  5. A triangle has a base of 8 inches and a height of 11 inches. What is its area?

    Answer: 44 sq in

    Area of a triangle = ½ × base × height = ½ × 8 × 11 = 44 square inches.

  6. What type of angle measures exactly 90°?

    Answer: Right angle

    A right angle measures exactly 90°, often indicated by a small square in diagrams.

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

    Answer: 282.6 cm³

    Volume = π × r² × h = 3.14 × 9 × 10 = 282.6 cm³.
