Answer:

Answer:when the light house spreads a red coloured light underwater .It forms a sector of angle 80⁰ and radius =16.5Km

Answer:when the light house spreads a red coloured light underwater .It forms a sector of angle 80⁰ and radius =16.5KmTherefore, area of sector =θ/360×pie×r²

Answer:when the light house spreads a red coloured light underwater .It forms a sector of angle 80⁰ and radius =16.5KmTherefore, area of sector =θ/360×pie×r²=area of sector =80/360×3.14×16.5×16.5

Answer:

Area of the sea over which the ships are warned is 188.07 sq.km.

Step-by-step explanation:

If you understand the question well, you'll come to know it is actually asking the area of the sector of the sea over which ships are warned.

theta = 80°, r = 16.5km

Area of a sector = (theta/360) x πr² ..... Formula

Area of a sector = (80/360) x 3.14 x (16.5)²

= (2/9) x 3.14 x 272.25

= 0.22 x 3.14 x 272.25

= 0.6908 x 272.25

= 188.07 km²
