Question

Tommy decided to also make a sampler can with a diameter of 2 inches and a height of 3 inches. Tommy calculated that the area of the base was 4 pi squared inches, and multiplied that by the height of 3 inches for a total volume of 12 pi cubic inches. Explain the error Tommy made when calculating the volume of the can.

    Answer:

    Sample response: Tommy used the diameter instead of the radius in the formula to find the area of the base. The diameter needs to be divided by 2 to find the radius. The correct area of the base is 1 pi square inches. The correct total volume is 3 pi cubic inches.Step-by-step explanation:

    Explanation:

    Tommy calculated the area of the base by squaring the diameter, not the radius. If he’s going to use the diameter in the area formula, he needs to divide the result by 4.

      A = πr² = πd²/4
