Debbie's backyard deck cost $56.00 per square meter to build. The deck is 9 meters wide and 9 meters long. How much did it cost to build the deck?

$514.00

Step-by-step explanation:

56 x 2 = 112

112 x 4 = 448

448 + 56 - 514

so $514.00 is your answer.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
