Answer:
Option D = 16π/3 ft
Step-by-step explanation:
Arc length formula is written Mathematically as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
So, the arc length is 16π/3 ft
Hello from MrBillDoesMath!
Answer:
88
Discussion:
Angle Q is an inscribed angle so
measure angle Q = 44 =
(1/2) measure of intercepted arc.
In other words,
44 = 1/2 mST => multiply both sides by 2
m ST = 44*2 = 88
which is the second choice
Thank you,

Answer:
115°
Step-by-step explanation:
Angle CHF has a measure equal to the average of the arcs the chords intercept.
angle CHF = (arc CDF +arc AB)/2 = (190° +40°)/2
angle CHF = 115°
