Answer:
17.85 cm
Step-by-step explanation:
1) Area of a sphere formula:
2) Plug in A: 1000 = 
3) Simplify: 1000 = 12.56
4) Divide Each Side By 12.56: 79.61783439 = 
5) Take the Square Root of 79.61783439 to Solve for
: 8.922882628 = 
6) Double
to get the diameter: 8.922882628*2= 17.84576486
7) Round to the Nearest Tenth: 17.85 cm
