  1. A pipe has a diameter of 6 inches. What is its circumference? (Use π ≈ 3.14)

    Answer: 18.84 in

    Circumference = π × diameter = 3.14 × 6 = 18.84 inches.

  2. A parts bin contains 120 items. If 15% are defective, how many are defective?

    Answer: 18

    15% of 120 = 0.15 × 120 = 18 defective items.

  3. Convert 3/8 inch to a decimal.

    Answer: 0.375

    Dividing 3 by 8 gives 0.375.

  4. A rectangular floor is 20 feet long and 15 feet wide. What is its area?

    Answer: 300 sq ft

    Area = length × width = 20 × 15 = 300 square feet.

  5. A machine runs at 1,200 RPM. How many full rotations does it complete in 30 seconds?

    Answer: 600 rotations

    1,200 RPM ÷ 2 (for 30 seconds) = 600 rotations.

  6. A ratio of defective parts is 1:50. In a batch of 1,500 parts, how many are expected to be defective?

    Answer: 30

    1,500 ÷ 50 = 30 defective parts expected.
