Answer:49 cm
Step-by-step explanation:
Circumference of circle = 2πr
308 cm = 2πr
308 / 2 cm= πr
154 cm = 22r / 7 [ π = 22 / 7 ]
154 × 7 / 22 cm = r
7 × 7 cm = r
49 cm = r or radius

Answer:
Let the radius of the circle be x.
therefore,2 × 3.14 × x = 308 cm
or, 6.28 × x = 308 cm
308
or, x = --------
6.28
308 10
or, x = ---------- × -----
1 628
or, x = 4.90 (approx)
