The first letter has to be a k, so the first letter only has one option.
The second letter can be any letter, so there are 26 options. This is the same for the third and fourth letter as well.
To find all possible options, you must multiply all of these "options" together.
1•26•26•26=17576

Please really need the correct answer for this or I'll fail algebra 3
trapecia [35]

Answer:

4\pi

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation x*\frac{\pi }{180}, x = 72

S =  72*\frac{\pi }{180} * R

given that R = 10

S = \frac{72*10*\pi }{180}

S = \frac{720*\pi }{180}

We simplify 720 as 180 goes into 720 4 times and we get

S = 4\pi

Hope this helps
