Answer 1

r ≈ 31.5 cm

Explanation:

The arc of a circle is calculated as

arc = circumference of circle × fraction of circle

Here arc = 22 , then

2πr ×
`(40)/(360)` = 22

2πr ×
`(1)/(9)` = 22 ( multiply both sides by 9 to clear the fraction )

2πr = 198 ( divide both sides by 2π )

r =
`(198)/(2\pi )` ≈ 31.5 cm
