In RT △ ABC, ∠ C = 90 °, AC = 8, BC = 6, two equal circles ⊙ a, ⊙ B are circumscribed, then the sum of the areas of the two sectors (that is, the shadow part) in the figure is () A. 254πB. 258πC. 2516πD. 2532π

In RT △ ABC, ∠ C = 90 °, AC = 8, BC = 6, two equal circles ⊙ a, ⊙ B are circumscribed, then the sum of the areas of the two sectors (that is, the shadow part) in the figure is () A. 254πB. 258πC. 2516πD. 2532π

In ∵ RT △ ABC, ∠ ACB = 90 °, AC = 8, BC = 6, ∵ AB = 82 + 62 = 10, ∵ s shadow = 90 π × 52360 = 254 π
