Final answer:

The surface area of a sphere with radius 2 is approximately 50.2656 square units.

Step-by-step explanation:

The surface area of a sphere with radius 2 can be found using the formula:

A = 4πr²

where r is the radius of the sphere. Plugging in the value of r = 2, we get:

A = 4π(2)² = 4π(4) = 16π

Therefore, the surface area of the sphere is 16π square units. Since π is approximately 3.14159, we can calculate the surface area as:

A ≈ 16(3.14159) = 50.2656

So, the surface area of the sphere with radius 2 is approximately 50.2656 square units.
