Multiply every number by two to get to the next points. This new triangle cannot be congruent to the first one because congruent means it is exactly the same. The new triangle is similar because its measurements are different.

Hope this helps!

A tire on a toy car has a diameter of 8 cm if the toy car travels 12,560 cm approximately how many times does the tire rotate? U

Marina86 [1]

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, $\textrm{Total number of rotations} = \frac{\textrm{Total Area covered}}{\textrm{Area covered in 1 rotation}}$

= $\frac{12,560}{25.12} = 500$

The number of rotations completed by circle = 500.
