  1. A trapezoid has parallel sides of length 6 and 10 and a height of 4. What is its area?

    Answer: 32

    Area = ½(b₁ + b₂)h = ½(6 + 10)(4) = 32.

  2. What is the measure of each interior angle of a regular pentagon?

    Answer: 108°

    Each angle = (5 − 2) × 180° ÷ 5 = 540° ÷ 5 = 108°.

  3. A sphere has a radius of 3. What is its volume? (Use π ≈ 3.14)

    Answer: 113.04

    Volume = (4/3)πr³ = (4/3)(3.14)(27) = 113.04.

  4. Triangle ABC is rotated 90° clockwise about the origin. This transformation preserves which property?

    Answer: Size and shape (congruence)

    Rotation is a rigid motion, so the image is congruent to the original.

  5. In a right triangle, one acute angle measures 30°. What is the measure of the other acute angle?

    Answer: 60°

    The two acute angles in a right triangle sum to 90°, so 90° − 30° = 60°.

  6. What is the circumference of a circle with diameter 14? (Use π ≈ 3.14)

    Answer: 43.96

    Circumference = πd = 3.14 × 14 = 43.96.

  7. A square has a diagonal of length 8√2. What is the length of each side?

    Answer: 8

    For a square, diagonal = side × √2, so side = 8√2 ÷ √2 = 8.
