  1. In a circle, a line segment from the center to any point on the circle is called the what?

    Answer: Radius

    The radius connects the center to a point on the circle.

  2. What is the surface area of a cube with edge length 3?

    Answer: 54

    Surface area = 6s² = 6(3²) = 54.

  3. An angle measuring exactly 180° is called what?

    Answer: Straight

    A straight angle measures exactly 180°.

  4. Two parallel lines are cut by a transversal. Alternate interior angles are always what?

    Answer: Equal

    Alternate interior angles are congruent when lines are parallel.

  5. What is the volume of a cylinder with radius 2 and height 5? (Use π)

    Answer: 20π

    Volume = πr²h = π(2²)(5) = 20π.

  6. A quadrilateral with exactly one pair of parallel sides is a what?

    Answer: Trapezoid

    A trapezoid has exactly one pair of parallel sides.

  7. What is the measure of an angle that is supplementary to a 110° angle?

    Answer: 70°

    Supplementary angles sum to 180°, so 180° − 110° = 70°.
