B) $4.51
C) $45.54
D) $14.23

A

Step-by-step explanation:

S.P= O.P-D.P

= (14.54-4.51)$

= $10.03

4,524 gallons

Step-by-step explanation:

The volume of any cylinder is 

 π (radius)² (height) .

The pool's radius is 1/2 its diameter = 8 ft.  So its volume is

 π (8 ft)² (3 ft)

= π · (64 ft²) · (3 ft)

= π · 192 ft³

= 603.2 ft³ .

(603 ft³) · (7.5 gal / 1 ft³) = 4,524 gallons

Hope this helps :D
