Hi there!
To solve this problem, we need to multiply each number by 4 ft.
8×4=32

hi buddy
The length of an arc length can be calculated using the formula:
s = ra
where s is the lenght of the arc
and r is the radius of the circle
a is the central angle in radians
first converts degrees to radians
a = 60 ( pi / 180)
a = pi /3 =1.05
s = 21(1.05)
s = 22 mm is the length of the arc
