Answer 1

7.09

Explanation:

s = r∅ = 7.09

s = (7 cm)(1.0123) = 7.086

58 deg x π/180 = 1.0123 radians

Answer 2

CB ≈ 7.09 cm

Explanation:

the length of arc CB is calculated as

AB = circumference of circle × fraction of circle

= 2πr ×
`(58)/(360)` ( r is the radius )

= 2π × 7 ×
`(29)/(180)`

=
`(14\pi (29))/(180)`

≈ 7.09 cm ( to 2 decimal places )
