The radius of a spherical ballon, of 30units , increases at the rate of 2units per second. then it's curved surface area increase by?

the answer is given as 480pie sq units/sec.

but for spheres
for r=30, CSA= 3600pie sq units.

for r=32, CSA = 4096pie sq units.
so, change in CSA = 496pie sq units/sec.
why is this wrong?
