Sagot :

Answer:
5) 18.8 cm
7) 49.5 ft

Explanation:
The formula for arc length is S = θ * r

5) S = 18 cm * Pi/3 (60 degrees in radians)
S = 6 Pi cm
S ≈ 18.8 cm


7) S = 9 ft * 7 Pi / 4
S = 63 Pi ft / 4
S ≈ 49.5 ft

Length of arc=r[tex]\theta[/tex]

So

#1

[tex]\\ \rm\Rrightarrow Area=18(\pi/3)=6\pi cm[/tex]

#2

[tex]\\ \rm\Rrightarrow Area=9(7\pi/4)=63\pi /4ft[/tex]
