Given that:
we get that:
Now, recall that the interior angles of a triangle add up to 180°, therefore:
Substituting:
in the previous equation, we get:

Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
A bicycle tire has a diameter of 62 cm. What is the distance the bicycle tire travels in 10 revolutions? Round your answer to the nearest centimeter
step 1
Find the circumference of the bicycle tire
we know that
The circumference of a circle is equal to
where
D is the diameter
we have
substitute
step 2
What is the distance the bicycle tire travels in 10 revolutions?
we know that
One revolution subtends a distance equal to the circumference of the bicycle tire
so
Multiply the circumference by 10

$ 40 ..... 100 %
$ 28 ..... x %
The % of change is 70 %.
This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:
$ 28 ..... x %
The % of change is 70 %.
This is equivalent with:
