My apologies. Let's calculate the surface area of the pincushion.

The formula for the surface area of a sphere is:
Surface Area = 4πr^2
where r is the radius of the sphere.

Given that the circumference is 6 cm, we can find the radius using the formula for the circumference of a sphere:
Circumference = 2πr
6 = 2πr
r = 3/π ≈ 0.955 cm

Now we can calculate the surface area:
Surface Area = 4π(0.955)^2
Surface Area ≈ 11.47 cm^2

So, the surface area of the pincushion is approximately 11 cm squared.
