Find the radius or diameter of a circle

Full solution

Q. each of the following figure erimeter and area of each

\newline

f are not drawn to scale.

Identify Equation Comparison: Identify the equation of the circle and compare it to the standard form. $\newline$ Equation given: $x^2 + y^2 = 36$ . $\newline$ Standard form of a circle: $(x - h)^2 + (y - k)^2 = r^2$ . $\newline$ Here, $h = 0$ , $k = 0$ , and $r^2 = 36$ .
Calculate Radius Value: Calculate the value of $r$ by taking the square root of $r^2$ . $r^2 = 36$ .Take the square root on both sides: $r = \pm\sqrt{36}$ . $r = \pm6$ .
Determine Appropriate Radius: Determine the appropriate value for the radius. Since radius cannot be negative, $r = 6$ .
