The answer is 314cm². The formula for the surface area of a sphere is: A=4πr². A=4×3.14×5² First solve for exponents. A=4×3.14×25 Then multiply. A=314cm²

surface area of a sphere is roughly 4 times the area of a circle with same readius aka SA=4pir^2 pi=3.14 for this problem r=5 SA=4*3.14*5^2 SA=4*3.14*25 SA=100*3.14 SA=314 answer is 314 cm^2
