Question

I want to paint all three walls of the kitchen. One was a half cylinder. I want to paint the walls only not the ceiling. The walls are 9-foot high how many square feet will I be painting round to the nearest tenth ​

Answer 1

Answer:

$490.9\ ft^{2}$

Step-by-step explanation:

we know that

The total area is equal to

$A=10(h)+2\pi r(h)+10(h)$

we have

$h=9\ ft$

$r=5.5\ ft$

$\pi=3.14$

substitute

$A=10(9)+2(3.14)(5.5)(9)+10(9)$

$A=490.9\ ft^{2}$
