To find the area of the top surface of the drum, we need to find the area of a circle with a diameter of 32 cm.
The formula for the area of a circle is:
A = πr^2
where A is the area, and r is the radius of the circle.
We know that the diameter of the drum is 32 cm, so the radius (r) is half of that:
r = d/2 = 32/2 = 16 cm
Now we can use the formula to find the area:
A = πr^2
= π(16)^2
= 256π
≈ 804.25 cm^2
Therefore, the area of the top surface of the drum is approximately 804.25 square centimeters.
