Sure, here are the steps to calculate the surface area of a sphere:

Step 1: Understand the formula for the surface area of a sphere. The formula is A = 4πr², where r is the radius of the sphere.

Step 2: Given that the diameter D of the sphere is 14.4 cm, we can find the radius by dividing the diameter by 2. So, r = D/2 = 14.4 cm / 2 = 7.2 cm.

Step 3: Substitute the radius r into the formula. So, A = 4π(7.2 cm)².

Step 4: Calculate the surface area A. A = 4π(7.2 cm)² = 4π(51.84 cm²) = 206.61 cm².

So, the surface area of the sphere is approximately 206.61 cm².
