I don't understand how to do these:

1) What is the measure in radians for the central angle of a circle whose radius is 8 cm and intercepted arc length is 5.6 cm?

Enter your answer as a decimal in the box.

2) In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians. (As in 3π over 2)

What is the length of the arc?

3) In a circle with a radius of 9 yd, an arc is intercepted by a central angle of π/6 radians. (π over 6)

What is the arc length?

Use 3.14 for π .

Enter your answer as a decimal in the box.

4) In a circle with a radius of 26.9 m, an arc is intercepted by a central angle of 9π/5 radians. (9π over 5)

What is the arc length?

Use 3.14 for π and round your final answer to the nearest hundredth.

Enter your answer as a decimal in the box.

5) In a circle with a radius of 21 5/8 yd, an arc is intercepted by a central angle of 5π/6 radians. ( 21 with 5 over 8|| 5π over 6)

What is the arc length?

Use 3.14 for π and round your final answer to the nearest hundredth.

Enter your answer as a decimal in the box.

Thank you so much!!
