PLS HELP! TWO MATH QUESTIONS

Answer 1

There is a formula that relates the arc length of a circle of radius, r, to the central angle ,θ in radians. S = r(θ) where S is arc length, r is radius, and θ is the central angle.

So substituting into the formula for the first question we have: 5.4=6(θ) and solving for θ we get 0.9

Now for the second question substituting into the formula we have:
S = 6($\frac{3 \pi }{2}$)

Solving this for S we find the arc length to be 9π

Answer 2

Yeah I'm not sure but I think it's 6
