Calculating the surface area of a sphere is actually pretty easy!

Here’s the formula you need to use:

$$A = 4\pi r^2$$

Let’s break it down:

• A is the surface area
• r is the radius of the sphere
• π (pi) is about 3.14

So, if you know the radius (the distance from the center to the edge of the sphere), just plug that number into the formula.

For example, if the radius is 3 units:

1. Square the radius: This means you multiply it by itself. So, $3^2 = 9$.
2. Multiply by $4\pi$: So you’ll do $A = 4 \times \pi \times 9$. This gives you $36\pi$.

It’s really that simple! Just remember the formula, and you can find the surface area in no time!
