Question

    A cylindrical tank has a radius of 4 meters and a height

    of 6 meters. Calculate the total surface area of the tank.
    A 100π m² Correct Answer Incorrect Answer
    B 80π m² Correct Answer Incorrect Answer
    C 96π m² Correct Answer Incorrect Answer
    D 72π m² Correct Answer Incorrect Answer

    Solution

    Total surface area = 2πr(h + r) = 2π × 4 × (6 + 4) = 2π × 4 × 10 = 80π m². Answer: b) 80π m².
