Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.
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
