You left out the question. What do they want you to calculate? The tension in the string?
If so, multiply the mass by the centripetal acceleration.
A stopper tied to the end of a string is swung in a horizontal circle. If the mass of the stopper is 13.0 g, and the string is 93.0 cm, and the stopper revolves at a constant speed 10 times in 11.8s?
