Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r. 
[tex]4 \pi (5^2) = 4(3.14)*25 = 100 * 3.14 = 314[/tex]
I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
Surface area of a sphere can be calculated as:

Surface Area = 4πr²

r = 5cm
π = 3.14

Using the values we get:

Surface Area = 4(3.14)(5²) = 314 cm²

Thus, the surface area of the sphere is 314 cm²
