<span>First find the central angle A in degree.
Perimeter circle 2Pi*R --> 360 deg
Arc A = 14.13 --> x deg
(360*14.13)/2Pi*R = 5086.8/37.68 = 135 deg
The pendulum rotates 135 deg in 3 sec. Then, the angular velocity is : 135/3 = 45 deg/sec.
Hope this helps!

Answer:52-12=$40
1/8*40 = 5 hours.
Step-by-step explanation:
Here's one shortcut:
2.3×10^9=1000(2.3×10^6) because your adding 3 more zeros to 2300000
Step-by-step explanation:
- 8969kg/cm^3
- 20oz jar of$2.78
Let, the original price = x
x*20 /100 = 27
x = 2700/20 = 135
Original price was $135
