Final answer:

The actual length of the leaf is 1.09 cm when rounded to three significant figures, calculated by dividing the drawn length (6 cm) by the magnification (× 5.5).

Step-by-step explanation:

The actual length of the leaf is 1.09 cm when rounded to three significant figures, calculated by dividing the drawn length (6 cm) by the magnification (× 5.5).

To calculate the actual length of the leaf when the magnification is provided, you can use the following formula:

Actual Length = Drawn Length ÷ Magnification

In this case, the leaf drawn by the student measures 6 cm in length and the stated magnification is × 5.5. Using the formula above, the actual length of the leaf can be calculated as follows:

Actual Length = 6 cm ÷ 5.5 = 1.09091 cm

To express the answer to three significant figures, we round it to 1.09 cm. So, the actual length of the leaf is 1.09 cm.
