Solution
Solution Steps
Step 1: Identify the Standard Form of a Circle's Equation
The standard form of the equation of a circle with center \((h, k)\) and radius \(r\) is given by:
\[
(x - h)^2 + (y - k)^2 = r^2
\]
Step 2: Substitute the Given Values
Given the center \((3, 4)\) and radius \(r = 5\), substitute these values into the standard form equation:
\[
(x - 3)^2 + (y - 4)^2 = 5^2
\]
Step 3: Simplify the Equation
Calculate \(5^2\):
\[
5^2 = 25
\]
Substitute back into the equation:
\[
(x - 3)^2 + (y - 4)^2 = 25
\]
Final Answer
The standard form of the equation of the circle is:
