let the other leg be x
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x = 
= 
= 
× = 2 ← exact value
The mixed number as an improper fraction is 37/8
<h3>How to express the mixed number as an improper fraction?</h3>
The diameter is give as:
Diameter = 4 5/8
