56,000??
If you mean 56,000 then the nearest thousand is 56,000
Answer:
The number of rotations completed by tire = 500.
Step-by-step explanation:
The diameter of the tire of toy car = 8 cm
Now, DIAMETER = 2 x RADIUS
So, radius of the tire = D/2 = 8/2 = 4 cm
Now, Circumference of the Circle = 2πr
= 2 x 3.14 x 4 = 25.12 cm
Now, 
= 
The number of rotations completed by circle = 500.
Answer:
27-(2·9)=9 inches
Step-by-step explanation:
the door is 27 inches wide, and the distance from each end of the towel bar to the end of the door is 9 inches, so the towel bar would take up all of the door except the 2·9 inches, so the equation is 27-(2·9)=9 in
Answer:
c = 13
Step-by-step explanation:
pythogoras theorem
a² + b² = c²
5² = 25
12² = 144
25 + 144<em> </em>= 169
√169 = 13
c = 13
What you need to know for this case is that the linear velocity is defined as the product of the angular velocity by the radius.
We have then:
v = w * r
Substituting the values:
v = (45) * (15) = 675
v = 675 cm / min
answer:
The linear speed, in cm / min, of a point on the rim of the record is:
v = 675 cm / min
