Answer:
Step-by-step explanation:
To find arc length we use the formula s = r(theta)
Theta is the given angle in radians (in this case it’s 90°, which in radians is pi/2), r is the radius (8), and s is the arc length
Here’s what you should get:
s = 8(pi/2)
s = (8pi)/2
simplify:
s = 4pi
the arc length is 4[tex]\pi[/tex]
