WebJan 31, 2024 · As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 11.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 .
