Both are true.
I apologize if this is not what you meant.
The answers to the questions
Let x and x+1 represent the consecutive integers, then x is the other leg and x+1 is the hypotenuse (because the hypotenuse must be greater than its sides).
Use Pythagorean Theorem:
a² + b² = c²
(77)² + x² = (x+1)²
5929 + x² = x² + 2x + 1
5928 = 2x
2964 = x
x+1 = 2965
Answer: The other leg is 2964 m and the hypotenuse is 2965 m
27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)
27pi=84.823
rounded, 84.82
