Answer: 287 degree
Step-by-step explanation:
Area of a sector = θ/360 x pi r^2
Where pi = 22/7
Given that the
area = 40.8 square inches
radius = 8 inches
40.8 = θ/360 × 3.143 × 8 × 8
θ = (360 × 40.8)/201.06
θ = 73 degree
The measure of the central angle of the circle = 360 - θ
= 360 - 73
= 287 degree
