If the wheel has a diameter of 15 inches, its radius is half that, or 7.5 inches then.
a full turn, or a full cycle around the wheel, namely around the circle is 360° or 2π radians.
now, in one turn or cycle, it covered an angle of 2π, in 2 cycles it covered 2(2π), in 3 it did 3(2π) and in 4 of course 4(2π).
so, what is the arc's length, whose radius is 7.5 and its central angle is 8π?
well.... you already know that s = rθ, therefore then, s = (7.5) (8π).
Answer:
44%
Step-by-step explanation:
185/420 = 0.4405
0.4405 * 100 = 44.05%
Answer:
3
Step-by-step explanation:
Pepper Jackie has 12 picks, 1 out of every 4 pick is orange and the rest are green.
So there could be three groups of 4 each and in each group there is 1 orange.
There are 3 groups of 4 each that makes 12 (
)
Now, in each group there is 1 orange, so in three groups there will be
orange.
1 for each group.
