Answer:
Step-by-step explanation:
You need to solve the area sector of the bigger circle. Since we now the length of sector is 270, we can set up an equation.
Length of sector DC = 2r
270 = 2(8+OA) *(8+OA is the raidus of the bigger circle/sector)*
270/2 = 8 + OA (division)
135/ -8 = OA
135/ -8 = OB (because OA and OB are the raidus of the same circle, so they are congruent)
