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
7/9 divided by 5/6
whenever dividing , always flip over the second fraction
7/9*6/5
cross out 9 and 6 , divide by 3
9/3=3
6/3= 2
7/3*2/5
mutiply the numerators together : 7*2= 14
mutiply the denominators together: 3*5= 15
answer:
14/15
