WebThe direction of the Earth's North and South Celestial Poles rotate to different points on the Celestial Sphere with a 25,800 year cycle. The orbital axis of the Earth stays fixed in space but the rotational axis constantly changes direction. WebSolution: The radius of sector = r = 10 feet. Arc length = l = 12.56 feet. Area of the sector without an angle = l r 2 = 12.56 × 10 2 = 62.8 sq. feet. Perimeter of sector = 2 r + l = 2 ( 10) + 12.56 = 32.56 feet. Find the arc length of a sector having a radius of 5 …
