Answer:
Step-by-step explanation:
Since curved a face area of a cylinder = 2pie r h
Therefore According to the given condition the curve surface area of a cylinder= 2 * 22/7* r * 8
352 = 2 * 22/7 * r * 8
352/2= 22/7 * r * 8
176 = 22/7 * r * 8
176/8 = 22/7 * r
22 = 22/7 *r
22 * 7/22 = r
Therefore r = 7
