sam must paint his bedroom ceiling. the diagram below represents his bedroom ceiling and includes a circular light fixture with a diameter of 2 feet. a gallon of paint covers 16 square feet and costs $8.95. how much will sam have to spend on paint to cover the entire ceiling except for the light fixture? assume he cannot buy a fraction of a gallon of paint.

Don't you realize that we can't see the diagram and you haven't given the dimensions?

the length is 12 and the width is 9

12 by 9 = 108 square feet
Area of light fixture:
A = pi * r^2
A = 3.14 * 1^2
A = 3.14 sq. ft.
108  3.14 = 104.86 sq. ft.
104.86/16 = 6.55 gallons
7 * 8.95 = ?

wait ... is the 7 from 6.55?
so would the answer for 7 * 8.95 be
$62.65 ???

Funny, the REA's testware has this same question, ceiling dimensions 12/9 which is
108  the light fixture diameter 2 = area 3.14=104.86 sq ft, agreed. divided by 16 sq ft per gallon = rounded 7 gallons
their answer choices:
$44.75 $50.20 $38.50 $42.99
am i crazy or is it NONE of these !!!
