Answer:
15
Step-by-step explanation:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
c² = 225

c = 15
Answer:
3
Step-by-step explanation:
Using Pythagorean Theorem, 3² + 4² = 5²
ANSWER
The radius is 4
EXPLANATION
The given equation is:

We complete the square to get the expression in standard form:


We factor using perfect squares to get:

This implies that,

Comparing to

The radius is r=4
