A formula for arc length, s, given the radius, r and central angle, Ф (in radians) is s = r × Ф.
s = 8 × 3 = 24 inches
2/5/9 solved will be 0.4 repeating as a decimal, & 4/9 as a fraction
Answer:

Step-by-step explanation:
<em>Circumference Formula:</em>
<em>C=2πr</em>
The radius is half of the diameter...

Pi is
...


That would be 20,30,40,50,60,70,80,90,100,110,120,130. 200,150,300,250
650 + 250 = so the answer would be 900.
F(x) = k*x^2
You can find k using only the first point.
28 = k*2^2
7 = k
The constant of variation is 7.
