Answer:

Part A:

The surface area of a cylinder is given by

A=  6πr² if h= 2r

Part B:

Total Cost of covering the cylinder = Rate *2πrh + rate*2πr²

Cost of covering only the side = Rate *2πrh

Step-by-step explanation:

Part A:

The surface area of a cylinder is given by

A= 2πrh + 2πr²

Where h= height and radius = r

But we have the height twice as radius so h= 2r

So putting h= 2r we get

A= 2πr(2r) + 2πr²

A= 4πr² + 2πr²= 2πr²(2+1) = 2πr²(3)= 6πr²

Part B:

Cost = Rate * area of the wall + rate * area of the top and bottom

Cost = Rate *2πrh + rate*2πr²

Where area of the top and bottom= πr² +πr² =2 πr²

and area of the side = 2πrh

Multiplying both with the rate and then adding would give the total cost of materials needed to cover the outside of the cylinder and from top and bottom as well.

If  you do not need to cover top and bottom then the expression would be

Cost of covering only the side = Rate *2πrh

Part C:

Already done above.

Two angles are supplementary angles. One angle measures 58 degrees. The other angle measures 3n + 5 degrees. What is the value o
stepladder [879]

Answer:

39

Step-by-step explanation:

Angles are supplementary when they add up to 180.  So, we know the other angle that isn't 58 is 180-58=122.  Therefore, 122=3n+5\\3n=117\\n=39

lakkis [162]

If there were 49 cars in a line that stretched 528 feet, what is the average car length? assume that the cars are lined up bumper-to-bumper

Answer: We are given there are 49 cars

Also these 49 cars are in a line stretched 528 feet.

Now the average length of the car is:

Average length = \frac{(length-covered-by-49-cars)}{Number-of-cars}

                          =\frac{528}{49}=10.78

Therefore, the average length of car is 10.78 feet
