Acircular plate has a radius of 13 centimeters. what is the area of the plate? use 3.14 for π . cm²

Can anyone me with 32,33,36,37,and 40.

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.)

What expression is equivalent to log3(x+4)
