Answer:
<h2>a = 11</h2>
Step-by-step explanation:

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.
You multiply 31 by 100 because one meter equals 100 centimeters. Then that gives you 3100 which is what 31m equals to in cm.
