Question

Solve.
The diameter of a circle is 8 kilometers. What is the angle measure of an arc 3π kilometers long?

Answer 1

Half the diameter is the radius so the radius is 4 kilometers. We then use the formula:
\[Length = r \Theta\]
We know that the length is 3π kilometers so put it into the equation and solve
3π = 4θ

Answer 2

is that a 40?

Answer 3

3π = 4 theta, so
theta = 4/3π

Answer 4

I havent learned that. lol. So : 4(4/3\[\pi\])

Answer 5

\[\theta = \frac{ 4 }{ 3 } \Pi\]
Is the final answer

Answer 6

Oh ok thanks!
