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

The 2 in the middle is the one that I needed help <br> Please
r-ruslan [8.4K]

Answer:

The equation is p=34a+12, and a=7

Step-by-step explanation:

Perimeter is all of the sides added together

p=12a+6a+8+6a+8+10a-4

Combine like-terms

p=34a+12

Solve for a by making p equal to 250

250=34a+12

Subtract 12 from both sides

238=34a

Divide both sides by 34

7=a
