To find the area of a circle (which is the shape of the drum's surface), we use the formula:

Area = πr²

where r is the radius of the circle. The radius is half the diameter, so in this case, r = 17.6 cm / 2 = 8.8 cm.

Substituting the value of r into the formula, we get:

Area = π * (8.8 cm)² = π * 77.44 cm² = 243.28 cm²

So, the area of the drum's surface is approximately 243.28 square centimeters.
