If s denotes the length of the arc of a circle of radius r subtended by a central angle θ, find the missing quantity.
Problem 1 :
s = 6.24 meters, θ = 2.6 radians, r =?
Problem 2 :
r = 2/3 feet, s = 14 feet, θ =?
Find the length s. Round the answer to three decimal places.
Problem 3 :
Problem 4 :
Problem 5 :
Problem 6 :
For a circle of radius 4 feet, find the arc length s subtended by central angle 60˚. Round to the nearest hundredth.
Problem 7 :
A pendulum swings though an angle of 30˚ each second. If the pendulum is 35 inches long. How far does its tip move each second? If necessary, round the answer to two decimal places.
1) r = 2.4 m
2) r = 21 radians
3) Arc length is 7.854 yd.
4) Arc length is 2.88 cm.
5) Arc length is 1.745 m
6) Arc length is 4.19 ft
7) 18.3 inches
Here s is the length of arc.
Problem 1 :
s = 12π/5 ; θ = π/2 ; r = ?
Problem 2 :
s = 50π/3 in ; θ = 5π/6 ; r = ?
Problem 3 :
s = 7ft ; θ = 3π/4 ; r = ?
Problem 4 :
s = 20 cm ; θ = 2π/3 ; r = ?
Problem 5 :
s = 12 in ; θ = 5 ; r = ?
Problem 6 :
s = 7 in ; θ = 3 ; r = ?
Problem 7 :
s = 15 m ; θ = 270 ; r = ?
Problem 8 :
s = 8 yd ; θ = 225 ; r = ?
1) r = 24/5
2) r = 20
3) r = 196/66 ft
4) r = 105/22 cm
5) r = 12/5 in.
6) r = 7/3 in
7) 1/18 m.
8) 28.125 yd.
