This difficult because I can not seem to get the right answer. I first converted the radius in meters. The I put it in the equation v = 2 (pi) (r) / (T). I got it. 4299 m / s. The centripetal acceleration I plugged it into the formula a = v (squared) / radius. I have first 57 m/s2 but the right itsn’t. I do not know what else to wash tun.Es a clever kitchen for drying lettuce leaves after them. It consists of a cylindrical tank mounted so that they are rotated on its axis by turning a crank. The outer wall of the cylinder is perforated with small holes. They represent the wet leaves in the container and turn to turn the crank to the water. The radius of the container is 11 7 cm. When the cylinder is turned on first 71 revolutions per second, which is the amount of centripetal acceleration on the outside?

I got the same answer as you.
I finally found the answer. The rotation is 1.71 revolution per seconds; however, you must divided one over 1.71 and you will get the answer primarily in seconds. For instance, how many seconds would it be if it only made one revolution? That’s how you get it 1 over 1.71.
T= 1/f =1/1.71 your value for T is wrong.
