find the measure of the angle of the radius of the circle is 4 inches and the length of the arc is 8 pi.

1 answer:

4 0

Since the angle is in radians, then s = rθ.

$\bf \textit{arc's length}\\\\
s=r\theta \quad 
\begin{cases}
r=4\\
s=8\pi 
\end{cases}\implies 8\pi =4\theta \implies \cfrac{8\pi }{4}=\theta \implies 2\pi =\theta$

stepan [7]

So if you have 192 marbles and you want to group them in groups of 15 marbles each
you would see how many times 15's there are in 192 or how many 192's would go into 15

so 192/15 or
12 and 12/15
