Let's learn about a circle! 🎉 1️⃣ Imagine the center of the circle is a balloon 🎈 at point (0,3). 2️⃣ The radius is how far you go from the center to the edge. It's like walking 4 big steps 👣. 3️⃣ So, the circle has all points that are exactly 4 steps away from 🎈 at (0,3). 4️⃣ The equation for this circle is: $$ (x - 0)^2 + (y - 3)^2 = 4^2 $$ 5️⃣ That means: $$ x^2 + (y - 3)^2 = 16 $$ Great job! This is the circle with center (0,3) and radius 4.
