Answer:
E. None of the above
Step-by-step explanation:
Arc length = radius • angle in radians
30 deg = 0.523599 rad
L = 12 • 0.523599 = 6.28319
2π = 6.28319
Answer is E. None of the above
Answer:
Inverse proportionality relationship
Step-by-step explanation:
SInce I equals 50 divided by t, we see "t in the denominator, which corresponds to an INVERSE proportionality between these variables (I and t)
Answer:

Step-by-step explanation:
The point slope form of a line is
where
. We write

Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

Answer:
t = (A/sx) - r
Step-by-step explanation:
Solve for t like this:

Answer:
approximately 56.51 cubic inches
Step-by-step explanation:
volume of a cone = 1 / 3 × pi × radius^2 × height
= 1/3 × 22/7 × 7.29 × 7.4
= 56.5148 cubic inches
