Answer:
2
Step-by-step explanation:
The length of the arc is rθ, where r is the radius and θ is the angle (in radians) subtended at the centre of the circle. Check: when θ=2π, the circumference of a circle is 2πr.
The area of the sector is r²θ/2. Check: when θ=2π, the area of a circle of πr².
So...
area of sector = length of arc
=> r²θ/2 = rθ
=> r/2 = 1
=> r = 2
