Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)
The
<u>correct answer</u> is:
$5,000.
Explanation:
When it is first purchased, the depreciation expense is calculated using the formula:

The cost was $23,000; the salvage value was $3,000; and the useful life was 8 years:

This means the value of the vehicle depreciates $2500 per year.
After 4 years, the vehicle would depreciate 2500(4) = $10,000.
This makes the new value $23000-$10000 = $13000.
Reevaluating the depreciation expense at this point, we use $13000 for the "cost" (current value), $3000 is still the salvage value, and now the total useful life was 6; we take 4 off of this, since it has already been 4 years:

The depreciation expense in year 5 is $5,000.
Alright , so basically the permiter that is given is like this:
327+327 +258+258 cm = 1170cm
now this can also be written as: 2(327+258)cm =1170cm
wait, its given as 258 and 218 cm. the width should be same actually , then only you can simplify it in order to get it in an expression ( simplest form)
