Answer:

17cm

Step-by-step explanation:

Perimeter = 2r+rФ=77.91, Ф=148°=(148°×π)/180°=2.583radians

so, 77.91 = r(2+2.583)

-->r =17cm

Answer:

17 cm (approximately)

Step-by-step explanation:

Perimeter of sector AOB

 = r( \frac{148π}{180}  + 2) = 77.91

⇒r =  \frac{77.91}{( \frac{148π}{180}  + 2)} ≈17cm

Hope it helps!
