Find Radius: Find the radius of the circle by dividing the diameter by $2$ . $\newline$ Radius = $\frac{\text{Diameter}}{2}$ $\newline$ Radius = $\frac{6}{2}$ $\newline$ Radius = $3$
Calculate Area: Use the formula for the area of a circle, which is $A = \pi \cdot r^2$ . $A = \pi \cdot (3)^2$
Square Radius: Square the radius and multiply by $\pi$ . $\newline$ $A = \pi \times 9$ $\newline$ If using $\pi$ as $3.14$ , then $A = 3.14 \times 9$
Calculate Area: Calculate the area. $\newline$ $A = 3.14 \times 9$ $\newline$ $A = 28.26$
