Distance traveled = 70 m
Number of rotations = 29
We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m
Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768
In short, Your Answer would be: 0.8 m
Hope this helps!
Answer:
130
Step-by-step explanation:
X is the alternate corresponding angle to 50. 50+y=180
y=130
x and y = the same thing so 130 is the value of x
The minutes cancel out leaving you with:
= 3.2 revs per second.
The wheel does
3.2 revolutions per second.
3x + 3 - x + 4 = 21
3x - x = 2x
2x +3 +4 = 21
3 + 4 = 7
2x + 7 = 21
-7 -7
2x = 14

2 2
x = 7
