Answer:

Surface area = 207.24 in²

Step-by-step explanation:

Remember to always convert the diameter into a radius.

D = 6 in (divide it by two to get the radius) R = 3 in

Radius = 3 in

Formula:

SA = 2\pirh + 2\pir²

Solution:

SA = 2\pirh + 2\pir²

SA = 2(3.14)(3)(8) + 2(3.14)(3)

SA = 2(3.14)(3)(8) + 2(3.14)(9)

SA = 150.72 + 56.52

SA = 207.24 in²

GCF of 4x^2y^2, 3xy^4, and 2xy^2
allsm [11]
The greatest common factor would be xy^2 because these are the only factors that they all have in common. The second term only has 1 x, so only 1 x is part of the gcf.

The 1st and 3rd terms each have y^2 therefore making it part of the gcf as well.

What is 0.91 meter equal to 1 what?
telo118 [61]

Answer:2.986

Step-by-step explanation:

0.91 meter = 2.986 feet

Formula: multiply the value in meters by the conversion factor '3.2808398950132'.

So, 0.91 meter = 0.91 × 3.2808398950132 = 2.986 feet.

0.91 METER TO THE NEAREST FRACTIONS OR INTEGER OF FOOT:

3 feet (e* = 0.48%)

The latest values above are alternative ones for 0.91 meter. They are represented in the form of usable fractions (1

2

, 1

4

, 3

4

etc.) or of an integer. We show these results, when it is possible to convert them to a fraction or integer with a small error e* which means the maximum rounding error (positive or negative).

To calculate a meter value to the corresponding value in feet, just multiply the quantity in meter by 3.2808398950131 (the conversion factor).

Here is the formula:

Value in feet = value in meter × 3.2808398950131

Suppose you want to convert 0.91 meter into feet. Using the conversion formula above, you will get:

Value in feet = 0.91 × 3.2808398950131 = 2.986 feet

The Retread Tire Company recaps tires. The fixed annual cost of the recapping operation is $65,000. The variable cost of recappi
trasher [3.6K]

Part a) Total Cost

Total Cost for recapping the tires is the sum of fixed cost and the variable cost. i.e.

The total cost is ( $65,000 fixed) + (15,000 x $7.5)

=$65,000+$112,500

=$177,500  

Part b) Total Revenue

Revenue from 1 tire = $25

Total tires recapped = 15000

So, Total revenue = 15000 tires x $25/tire

Total Revenue =$375,000  

Part c) Total Profit

Total Profit = Revenue - Cost

Using the above values, we get:

Profit = $375,000 - $177,500

Profit = $197,500  

Part d) Break-even Point

Break-even point point occurs where the cost and the revenue of the company are equal. Let the break-even point occurs at x-tires. We can write:

For break-even point

Cost of recapping x tires = Revenue from x tires

65,000 + 7.5 x = 25x

65,000 = 17.5 x

x = 3714 tires

Thus, on recapping 3714 tires, the cost will be equal to the revenue generating 0 profit. This is the break-even point.
