Answer:

radius = 30 in

Step-by-step explanation:

EF = circumference × fraction of circle, substitute values

5π = 2πr × [tex]\frac{30}{360}[/tex] ← where r is the radius

5π = 2πr × [tex]\frac{1}{12}[/tex]

Multiply both sides by 12 to clear the fraction

60π = 2πr ( divide both sides by 2π )

[tex]\frac{60\pi }{2\pi }[/tex] = r, thus

r = 30 in

Length of arc = angle X r
Therefore
Change angle deg to rad
30 X pie/180 =1/6 pie

Put in equ
5pie = 1/6pie X r
r = 5pie / (1/6 pie )
r = 30
