I am supposing you are looking for k, in that case you add 4.05 to both sides of the equation to cancel out the 4.05 on the k side, making the equation k = 10.25
y / r2 = a constant (k) so k = 405/81 ie 5. k = y/4 when r = 2, so y = 20.
They are members of an infinite set of integers of the form 405*k where k is an integer.
21 of 62 is 33.87%
75 minus 13 equals 62.
62 meters = 67.8040245 yards

62-56 equals = 6
405 millimeters is 15.95 inches.
62 squared equals 3,844.
405
A common multiple of 9, 45 and 81 is a number of the form 405*k where k is any integer.

How about 2 times 31 = 62
