Answer:
Central angle = 98 degrees
Step-by-step explanation:
Radius (r) = 10 Arc length = 49[tex]\pi[/tex]/9
Let 0 be the central angle
Arc Length = 2[tex]\pi[/tex]r0/360
49[tex]\pi[/tex]/9 = 2[tex]\pi[/tex]r0/360
49[tex]\pi[/tex]/9 = [tex]\pi[/tex]x0/18
49[tex]\pi[/tex]/9 x 18/[tex]\pi[/tex] = 0
0 = 49x2
0 = 98 degrees
