Read the first 7 Area and Volume flashcards as text

  1. A cone has radius 3 cm and height 8 cm. What is its volume in terms of π?

    Answer: 24π cm³

    V = ⅓πr²h = ⅓ × π × 9 × 8 = 24π cm³.

  2. A sphere has radius 3. What is its volume in terms of π?

    Answer: 36π

    V = (4/3)πr³ = (4/3)π(27) = 36π.

  3. A triangle has base 15 ft and area 60 ft². What is the height?

    Answer: 8 ft

    A = ½bh → 60 = ½ × 15 × h → h = 120/15 = 8 ft.

  4. A rectangular room is 12 ft long and 10 ft wide. What area of carpet covers the floor?

    Answer: 120 ft²

    Area = 12 × 10 = 120 ft².

  5. A circle has area 49π. What is its radius?

    Answer: 7

    πr² = 49π → r² = 49 → r = 7.

  6. A cube has side length 4 cm. What is its surface area?

    Answer: 96 cm²

    Surface area = 6s² = 6 × 16 = 96 cm².

  7. A cylinder has volume 200π cm³ and radius 5 cm. What is its height?

    Answer: 8 cm

    V = πr²h → 200π = π × 25 × h → h = 200/25 = 8 cm.
