Best Answer: the circumference<span> of a </span>circle<span> is 2πr (where r= radius)</span>
<span>The arc length of a </span>quadrant of a circle<span> is a quarter of the</span>circumference, i.e. πr/2.
<span>There are also the lengths of the 2 straight sides of the </span>quadrant<span>, and their lengths are both r. so the </span>Perimeter<span> of a </span>quadrant<span>= 2r + (πr/2)</span>
Answer:
Sides: a = 122 b = 122 c = 122
Area: T = 6444.961
Perimeter: p = 366
Semiperimeter: s = 183
Angle ∠ A = α = 60° = 1.047 rad
Angle ∠ B = β = 60° = 1.047 rad
Angle ∠ C = γ = 60° = 1.047 rad
Height: ha = 105.655
Height: hb = 105.655
Height: hc = 105.655
Median: ma = 105.655
Median: mb = 105.655
Median: mc = 105.655
Inradius: r = 35.218
Circumradius: R = 70.437
Vertex coordinates: A[122; 0] B[0; 0] C[61; 105.655]
Centroid: CG[61; 35.218]
Coordinates of the circumscribed circle: U[61; 35.218]
Coordinates of the inscribed circle: I[61; 35.218]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 120° = 1.047 rad
∠ B' = β' = 120° = 1.047 rad
∠ C' = γ' = 120° = 1.047 rad
