Describe and correct the error in finding the area of a sector with a radius of 6 centimeters and a central angle of 40
Jet001 [13]

Answer:

12.56

Step-by-step explanation:

Remark

Since we don't have anything other than the question, all I can do is answer the question. You are left with the task of figuring out the error.

Formula

Area = (central angle divided by 360 ) * pi r^2

Solution

Area = (40 /360) * 3.14 * 6^2

Area = 1/9 * 3.14 * 36

Area = 4 * 3.14

Area = 12.56

oee [108]

Answer:

19 bars =<u> 76 more ores.</u>  22 bars = <u>88 total ores.</u>

y = 4x

(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)

1 b = 4 o

3 b = 12 o

22 - 3 = 19 b

19 b = 76 o (more)

22 b = 88 o (total)

You own an electronics store with a merchandise book value of $245,000. You conduct a physical inventory and find the value to b
Aleksandr-060686 [28]

0.22% shrinkage as a percent of sales.

To calculate shrinkage you subtract the physical inventory value from the book value.

245,000-237,000 = 800

The shrinkage was $800. To find the shrinkage as a percent of sales take the shrinkage value and divide it by the sales value to get shrinkage as a percentage of sales.

800 / 360,000 = 0.0022....

Multiply Decimal by 100 to get the percentage

100 * 0.0022.... = 0.22%
