Find the area of the shaded circle
WebThere are 8 circular segments, each of area π 2 r 2 ( θ − sin θ) where r is the radius, and θ is the angle subtended at the center by the segment. Here, from the geometry, r is clearly 1 c m and θ = π 2, each segment spanning half a semicircle. Therefore the shaded area is 8 π 2 ( 1 c m 2) ( π 2 − 1) = ( 2 π − 4) c m 2 Share Cite Web1 Answer Sorted by: 5 Sides of a 30-60-90 triangle of hypotenuse 16 are 8 and 8 3. The area of that triangle is then ( 1 / 2) ( 8) ( 8 3) = 32 3. The shaded area is then the area of the circle minus the area of that triangle, or 64 π − 32 3.

WebJul 23, 2015 · The area of the major circular sector subtending at the center an angle 2 π − π 3 = 5 π 3 = 1 2 ( 5 π 3) ( 12) 2 = 120 π Hence, the area of the shaded portion = area of (red) triangle + area of major sector = 36 3 …
WebSo the area of the sector over the total area is equal to the degrees in the central angle over the total degrees in a circle. And then we just can solve for area of a sector by multiplying both sides by 81 pi. 81 pi, 81 pi-- so these cancel out. 350 divided by 360 is 35/36. And so our area, our sector area, is equal to-- let's see, in the ... WebCalculate the area of the shaded region.
