Game 1
Circumference=Diameter × pi
Circumference=27.3×3.14
Circumference=85.722
Circumference~=86 cm

Game 2
Circumference= Diameter × pi
Circumference=22.5 × 3.14
Circumference=70.650
Circumference~=71cm

Game 1- Game 2
86-71
15
Thus the circumference of the flying disc the first game is 15cm greater that that of game 2.

First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65=85.722 and 2*3.14*11.25=70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.

The table and graph both represent
valina [46]

I'm not sure what your table and graph look like but they might both represent the relationship between numbers, like the common difference (+5 ect) They could also both represent  positive growth or negative growth depending on how the graph and table look.

Hope this helps!

Answer:

694 ft²

Step-by-step explanation:

Calculate the area of all 6 walls, noting that the front and back faces are congruent as are the 2 side faces and top/bottom faces

area = 2(13 × 8.5) + 2(11 × 8.5) + 2(13 × 11)

       = 221 + 187 + 286 = 694 ft²

GuDViN [60]
Y - y1 = m(x - x1)
slope(m) = 3/4
(-4,6)....x1 = -4 and y1 = 6
now just sub...and pay attention to ur signs
y - 6 = 3/4(x - (-4)...not done yet
y - 6 = 3/4(x + 4) <===
