Answer:
88.49 units²
Step-by-step explanation:
Use the formula for the area of a sector.
A = (1/2)r²·θ
where θ is the central angle of the sector in radians, and r is the radius.
Here, the central angle of the sector is 360°-300° = 60° = π/3 radians. Then the area is ...
A = (1/2)(13)²(π/3) = 169π/6 ≈ 88.49 . . . . units²
