Answer:
ummm well that hard let me solve it real quick
Step-by-step explanation:
:/
A = pi r^2 78.5 = pi r^2 r = sqrt(78.5/pi) arc length in radians 6 pi cm / (sqrt(78.5/pi) cm/rad) = 3.77 rad or 3.77 rad / (pi rad / 180°) = 120° i assumed that you meant 6 pi cm for arc and the central angle is equal to subtended arc measure.
hope this helps !

(-5x^5)(a) = 25x^7 + 100x^5
<u>+5x^5 +5x^5</u>
a = 25x^7
