Question

HELP HELP HELP HELP BEEN STUCK FOREVERRR

Answer 1

Answer:

r ≈ 31.5 cm

Step-by-step explanation:

The arc of a circle is calculated as

arc = circumference of circle × fraction of circle

Here arc = 22 , then

2πr × $\frac{40}{360}$ = 22

2πr × $\frac{1}{9}$ = 22 ( multiply both sides by 9 to clear the fraction )

2πr = 198 ( divide both sides by 2π )

r = $\frac{198}{2\pi }$ ≈ 31.5 cm
