To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
In this problem we have double parentheses. Which one should we solve first? The answer to that is always the inner most ones:
13[ 6² ÷ (5² - 4²) + 9]
5² - 4²
^^^Here you will have to first take the square of both values
25 - 16
9
13[ 6² ÷ (9) + 9]
Now for the exponents
13[ 6² ÷ (9) + 9]
6²
36
13[ 36 ÷ 9 + 9]
Now for the division:
13[ 36 ÷ 9 + 9]
36 ÷ 9
4
13[ 4 + 9]
Now for the addition
13[ 4 + 9]
4 + 9
13
13[13]
Now for multiplication
169

The volume of the sphere in cubic inches is option D) 1767.1
<u>Step-by-step explanation</u>:
Given,
The diameter of the sphere = 15 inches
The radius of the sphere, r = diameter/2
=15/2
r =7.5 inches
The volume of the sphere = 4/3 πr^3
⇒ 4/3 π(7.5)^3
⇒ 4/3
3.14
421.86
⇒ 1766.25 cubic inches
⇒ 1767 cubic inches (approximately)
