Answer:
If I am correct then the answer should be 268 in2
Step-by-step explanation:
recall that the radius is the distance from the center of a circle to any point on the circle.
we know the center is at -16,-14, and we know that -8,-8 is a point on the circle, so the distance between both must be the radius.

--------------------------------------------------
Option 2: Fraction to percentage: x100
---------------------------------------------------
5/7 x 100 = 71.4%
--------------------------------------------------
Option C: Fraction to percentage: x 100
---------------------------------------------------
12/5 x 100 = 240%
--------------------------------------------------
Option D: Decimal to percentage: x 100
---------------------------------------------------
1.4 x 100 = 140%

Answer:
side of the mosaic = 7 inches
Step-by-step explanation:
Diego has 49 square inch tiles. He wants to use to make a square mosaic.
Area of the tile = 49 square inches
We know , area of the square = s^2
where 's' is the side of the square
Plug in 49 for area and solve for 's'
Take square root on both sides
s= 7
side of the square = 7 inches
Answer:
x=6 2/3
