Answer 1

the length of the arc is 2 cm

Explanation:

im doing this right now

Answer 2

The length of arc S = 47.1

Explanation:

The radius of the circle = 10

The central angle of the arc = 3

By formula, S = rΘ

where S is the lenth of the arc

r is the radius of the circle

Θ is the central angle of the arc

substituting the values in the formula, we get

S = rΘ = 10 (3) = 15 = 47.1
