Use the arc length formula and the given information to find r.
s = 12 cm, θ = 36°; r = ?

thirty divided by pi cm
sixty divided by pi cm
one third cm
one hundred twenty divided by pi cm

Step-by-step explanation:

The thing with the arc length formula, s = rt, is that t is the angle in radians.  Ours is in degrees, so we have to change it:

36 ×

So the formula we use to solve for r is:

Multiply both sides by 5 over pi to get that

96 39 cause 135 -96=39 im smart (i used a calculater)

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
