Answer:
<h2>a₈ = 1</h2>
Step-by-step explanation:
Step-by-step explanation:
Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.
so,
AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45
AB = sqrt(45) ≈ 6.7
CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40
CD = sqrt(40) ≈ 6.3
16/25 is the simplified answer
Answer:
1.047 ft
Step-by-step explanation:
The length of an arc is given by ...
s = rθ
where s is the arc length, r is the radius, and θ is the central angle in radians. Your arc subtends an angle of 12° = (12·π/180) = π/15 radians. The length of the arc is then ...
s = (5 ft)(π/15) = π/3 ft ≈ 1.047 ft
