WebSolution: We know that the central angle = 120 ∘, and the arc length is 8 inches. Using the formula, Central Angle = s × 360 2 π r. where, “ s ” is the length of the arc, and “ r ” is the radius of the circle. 120 ∘ = 8 × 360 2 π r. r = 8 × 360 2 π × 120. r = 2880 753.6. r = 3.821. The radius of the arc is 3.821 cm. WebThese five components were vertices, (a location where 2 or more edges meet), faces (contained and defined by 3 or more edges), edges (defined as the “ridge or sharp edge” [2] of a polyhedron), sides (used to refer to the sides of each face), and plane angles (the angle found at a vertex, contained by 2 sides).
