Question 9
The pictured ball is modelled as a sphere of diameter 3 inches. Find its surface area in square inches, rounded to the nearest whole number. AI reconstruction: treat the labelled diameter as exact and round to a whole square inch; this is an idealized pictured ball, not a claim about regulation tennis-ball size. Original choices: A:14; B:18; C:22; D:26; E:30 square inches. Enter the corrected number.
