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).
Part A is “50”.
Part B is “A and E”
Answer:
480 miles
Step-by-step explanation: 4 times 120
1 hour = 3600 seconds
3 × 3600 = 10800
<span>10800 yards per hour
</span>
1 mile = 1760 yards
10800 ÷ 1760 = 6.13
6.13 miles per hour
Answer:
not sure if u saw the comment but
7 and 8 are congruent, and 8 is congruent to 10
that maybe the rest of the answer
