What is the length of the arc of we know the radius of curvature is 12 inches and the area of the sector created is 252inches

Asquare parking lot has 6,400 square meters what is the length in meters

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Pls the last one and it has to be like number 6
