The formula for arc length is l = θr. θ is the angle in radians and r is the radius of the circle. Plugging in we get pi over 2 all times 4. 4 over 2 reduces to 2. Finally, our answer is 2pi
First you subtract three from three and -29 then you divide that by -2
Answer:
f(-7) = 2
Step-by-step explanation:
f(x) = x + 9
We want to find f(-7)
f(-7) = -7 + 9
-7 + 9 is the same thing as saying 9 - 7
9 - 7 = 2
So f(-7) = 2
