If we were to put a distinguishing mark on a specific random place on the tire, right at the point where the tire meets the ground for example, when the car starts moving, the tire has made one full revolution when that same mark meets the ground again. That is also known as the circumference of a circle...one time around the circle. The formula for the circumference of a circle is
.
We are given a radius of 13 inches and are told to use 3.14 for pi. That means that our formula looks like this:
and C = 81.6 inches, That's how far the tire travels every time it turns exactly once.
Answer:
23
Step-by-step explanation:
Answer:
The equation you should solve to find b is:
Option D. sin 35° / 9 = sin 40° / b
Step-by-step explanation:
m<A=35°
m<B=40°
a=9
b=?
We can use the Law of sines:
sin A / a = sin B / b
Replacing the given values:
sin 35° / 9 = sin 40° / b
This is option D.
