  1. What is the area of a circle with diameter 10 cm? (Use π ≈ 3.14)

    Answer: 78.5 cm²

    Radius = 5 cm; Area = πr² = 3.14 × 25 = 78.5 cm².

  2. A right angle measures exactly how many degrees?

    A right angle is defined as exactly 90°.

  3. What is the surface area of a rectangular box that is 3 cm × 4 cm × 5 cm?

    Answer: 94 cm²

    Surface area = 2(lw + lh + wh) = 2(12 + 15 + 20) = 2 × 47 = 94 cm².
