Answer:
32 and 56?
Step-by-step explanation:
32 and 56 are related to 8.
32=8x4
56=8x7
Two, 2 and 7, because 3/11 just equals 0.2727272727..., so the two and seven keep repeating
Answer:
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
Step-by-step explanation:
step 1
Find out the area of the room
The area of the rectangular room is

step 2
Find out the area of the circular rug
The area of the circle is

we have

----> the radius is half the diameter
substitute


step 3
Find out what percentage of the room is not covered by the rug
we know that
300 ft^2 represent the 100%
so
using proportion
Find out what percentage represent the difference (300-28.26)=271.74 ft^2
Let
x ----> the percentage not covered by the rug

Convert to fraction form

Simplify

therefore
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
Answer:
As shown in picture,
Angle CDF = Angle BDE = 54 deg (pair of opposite angles)
Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).
=> Arc CB = Angle CDB = 126 deg (property of angle on circle)
Hope this helps!
