Ответ:
x = 0.5
Step-by-step explanation:
Area of a circle = πD²/4
Area of an arc section = (½θ)R²
θ = 45° = π/4 radians
as the two shaded areas are reported as equal
π(4 - 4x)²/4 = ½(π/4)(10x - 2)² - ½(π/4)(6x - 2)²
(4 - 4x)² = ½(10x - 2)² - ½(6x - 2)²
16 - 32x + 16x² = ½[(100x² - 40x + 4) - (36x² - 24x + 4)]
16 - 32x + 16x² = ½(64x² - 16x)
16 - 32x + 16x² = 32x² - 8x
16 - 24x - 16x² = 0
quadratic formula
x = (24 ±√(24² - 4(-16)(16))) / (2(-16))
x = (24 ± 40)/-32
x = -2
which we ignore as it would make the radii on our arc section negative.
or
x = 0.5
The shaded area represents π units² in area
