The Area is 81 [tex]in^{2}[/tex]. Lets see the solution.
Given:
π=[tex]\frac{22}{7}[/tex]
r=10.7
∅ = 77°
Solution :
= [tex]\frac{∅}{360°}[/tex]×π[tex]r^{2}[/tex]
=[tex]\frac{77}{360}[/tex]×[tex]\frac{22}{7}[/tex]×[tex]11^{2}[/tex]
= [tex]\frac{11}{360}[/tex]×22×121
=[tex]\frac{11^{2} }{180}[/tex]
Area =[tex]81in^{2}[/tex]
