Thank you for the opportunity to help you with your question!

Area of sector = 1/2 *radius ( in radians) * angle

10 = 1/2  * (3)^2 * angle 

angle = 20/9 .radians.......................................ANSWER

          = 2.22 radians..................................ANSWER

we can also write this answer in degree

20/9 radians = 20/9  * 180/ pi  degrees
