#361pi units^2#

Explanation:

#Circumference=19pi#

#Diameter = (Circumference)/pi =(19pi)/pi=19#

#Radius=(Diameter)/2=19/2=9.5#

#Surface area of sphere=4pir^2=4pi(9.5)^2=361pi units^2#

I gave the answer in #units^2# because you did not provide the measuring unit of the circumference of the sphere.
