A) x * y = 42 (or x = 42/y)
B) x + y = 23
B) 42/y + y = 23
42 + y^2 = 23y
y^2 -23y + 42 = 0
The numbers are 21 and 2

Hypothesis testing
For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:
Using a t-statistics table, or using the function TDIST in Microsoft Excel with with two-tailed distribution, we obtain .
A=r^ 2 * pi=35^ 2 *3.14=3846.5m
