Answer 1

Answer:

apply formula for length of arc

= theta /360 × 2πr.

here we know theta = 60.

and r(radius)= 21cm.

put all the values.

60/360× 2×22/7×21.

1/6×6×22.

22 cm.

I hope its correct.

Answer 2

Answer:

22cm

Step-by-step explanation:

As you may know,

Angle= Arc/Radius

here, the question asks for Arc

so formula becomes

Arc= angle× radius

now..

angle is 60° which can be written as π/3.. so when we multiply

π/3 × 21, we get 7π

now, π= 22/7 , so we get 22/7×7 which equals to 22cm..

hope this helps
