  1. What is the area of a parallelogram with base 9 and height 5?

    Answer: 45

    Area = base × height = 9 × 5 = 45.

  2. What is the volume of a cone with radius 3 and height 4? (use π ≈ 3.14)

    Answer: 37.68

    Volume = ⅓πr²h = ⅓(3.14)(9)(4) = 37.68.

  3. What is the area of a circle with diameter 10? (use π ≈ 3.14)

    Answer: 78.5

    Radius is 5, so area = πr² = 3.14(25) = 78.5.

  4. What is the perimeter of a rectangle with length 12 and width 7?

    Answer: 38

    Perimeter = 2(l + w) = 2(12 + 7) = 38.

  5. What is the sum of the interior angles of a pentagon?

    Answer: 540

    Sum = (n − 2)180 = (5 − 2)180 = 540.

  6. What is the volume of a rectangular prism 3 by 4 by 5?

    Answer: 60

    Volume = length × width × height = 3 × 4 × 5 = 60.

  7. What is the area of a triangle with base 10 and height 6?

    Answer: 30

    Area = ½ base × height = ½(10)(6) = 30.
