area of a sector of a circle of radius 36 cm is 54 pie cm square . find the length of the corresponding arc of the sector

Answer 1

i need the answer

Answer 2

can you not look up the formulas?

a = 1/2 r^2 θ, so
1/2 (36^2) θ = 54 pi (not pie!)
θ = 108π/1296 = 0.2618

now for the arc length,

s = rθ = 36 * 0.2618 = 9.42

Answer 3

9.43 cm
