I don't understand this question. Could anyone excplain to me what it wants me to do and what the answer is?

What is the diameter of a sphere that has a surface area of 1041 square inches?

A) 9.1

B) 22.5

C) 40.3

D) 18.2

The answer is 18.2

I got the answer by solving it

1st you need equation for the surface area of a sphere which is:

A=4*π*r^2

Where r=radius

r = diameter/2 or d/2

So

area of a sphere = 4*π * (d/2) ^2

Plug in the area given

1041 = 4*π * (d/2) ^2

Solve for d

1041 / (4 * π) = 82.84

82.84 = (d/2) ^2

Sqrt (82.84) = d/2

9.10=d/2

9.10*2 = d

18.2=d

So the answer is 18.2 in
