Answer:
Step-by-step explanation:
you need the arc length formula .. do you have it?
s = r ∅
s is the arc length in radians but you can make it in degrees just by
using s = 2πr (θ/360)
the angle is 180 for the picture.
so the arc length is just 
r
r= 4
*4 = 12.56637.... approx
Answer:
(f-g)(4) = 10
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
= 1/2 x^2 - 1/4 x + 4 - 1/2 x + 1
= 1/2 x^2 - 1/4 x - 1/2 x + 4 + 1
= 1/2 x^2 - 3/4 x + 5
(f-g)(4)
= 1/2 (4)^2 - 3/4 (4) + 5
= 1/2 * 16 - 3 + 5
= 8 - 3 + 5
= 5 + 5
= 10
