The formula for the surface area of a sphere is 4πr².

Step 1: Identify the radius. In this case, the radius (r) is given as 5 units.

Step 2: Substitute the radius into the formula. So, it becomes 4π(5)².

Step 3: Calculate the square of the radius. 5² = 25.

Step 4: Multiply the result by 4π. 4π * 25 = 100π.

Step 5: Since we are using 3.14 for π, multiply 100 by 3.14. 100 * 3.14 = 314 units.

So, the surface area of the sphere is 314 units. However, none of the given answer choices match this result. There might be a mistake in the question or the answer choices.
