Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:

Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:

This is given in radians, so
is 4 radians
D is the correct answer choice.
Answer:
d
Step-by-step explanation:
So the problem states,
52 = 36 + 4x
16 = 4x
x = 4 (must be less than or equal to)
Answer:
48 minutes
Step-by-step explanation:
Pete: 3 hours = 2 hours 60 minutes
Sheila: 2 hours 60 minutes - 55 minutes = 2 hours 5 minutes = 1 hour 65 minutes
Mark: 1 hour 65 minutes - 1 hour 17 minutes = 48 minutes
Answer:
choice 4) 33.5 in³
Step-by-step explanation:
r = 4/2
V = 4/3πr³ = 4/3(3.14)(2³) = 33.5 in²
Answer:
12
