A square barn measures 42 feet on each side. A goat is tethered outside by a rope that is attached to one corner of the barn, as shown in the bird's eye sketch. a. suppose the length of the rope is 28 feet. How many square feet of land is the goat able to gaze

b. suppose the length of the rope is made twice as long as in part a. How many square feet of land is the goat now able go gaze

(answer both questions, not just one )
Here's an image that would help

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
