Additive Identity Property is the answer.
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:
6.71
Step-by-step explanation:
Use the Pythagorean Theorem with the triangle:
6^2 + 3^2 = x^2
x = 6.71
