  1. What is the area of a circle with a radius of 7?

    Answer: 49π

    The area of a circle is A = πr², so π × 7² = 49π.

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

    Answer: 120°

    The interior angle of a regular polygon = (n - 2) × 180° / n = (6 - 2) × 180° / 6 = 120°.

  3. A right triangle has legs measuring 5 and 12. What is the length of the hypotenuse?

    Answer: 13

    Using the Pythagorean theorem: √(5² + 12²) = √(25 + 144) = √169 = 13.

  4. What is the volume of a rectangular box with dimensions 4 × 6 × 3?

    Answer: 72

    Volume = length × width × height = 4 × 6 × 3 = 72 cubic units.

  5. Two angles are supplementary. One angle measures 65°. What is the measure of the other angle?

    Answer: 115°

    Supplementary angles sum to 180°, so 180° - 65° = 115°.

  6. What is the perimeter of a square whose area is 64 square units?

    Answer: 32

    The side length is √64 = 8, and the perimeter of a square is 4 × side = 4 × 8 = 32.

  7. What is the circumference of a circle with a diameter of 10?

    Answer: 10π

    Circumference = π × diameter = π × 10 = 10π.
