345.8
523.6
1436
205.1

hint Hint:

The tennis ball is a sphere.
The volume of a sphere is given by $4 over 3 cross times straight pi cross times left parenthesis radius right parenthesis cubed$

The correct answer is: 1436

Volume $equals 4 over 3 πr cubed$
$equals 4 over 3 cross times straight pi cross times 7 cubed equals 1436 space inches cubed$
