Gabriela plans to carpet
her living room, except for
the quarter-circle shown in
the corner. That area will
be a wood floor where she
will put her piano. The
radius of the quarter circle
is 8 feet. If carpeting costs
$9.55 per square foot, what
is the cost of the carpeting
she will use in her living
room?

if you need just tell me and i will come to the rescue.

step-by-step explanation:

its wrong

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
