Okay! A cylinders area is found by the following equation.

A = πr²h

We need to find the radius, which is half of the diameter. So the radius is 5.5 in.

A = π(5.5)²h

There is no provided height in the question you asked, but I will simplify as much as possible so if you have the height, you can simply plug it in!

A = 30.25πh in³

Remember π is the symbol for the irrational number 3.1415... Regardless, plug that into a calculator with the provided height and you’ll have your answer.

Write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Levart [38]

Answer:

y = 3x - 14

Step-by-step explanation:

Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.

Plug in the slope and given point into y = mx + b, then solve for b:

y = mx + b

4 = 3(6) + b

4 = 18 + b

-14 = b

Plug in the slope and y intercept into y = mx + b

y = 3x - 14

So, the equation of the line is y = 3x - 14

The digit in the tens place of a two digit number is three times that in the units place. If the digits are reversed the new num
S_A_V [24]
We could do it with algebra.  But we can also do it the long way, which is
shorter than the algebraic way.

The digit in the tens place is 3 times the digit in the units place.
So the number MUST be
31, or
62, or
93 .
It can't be anything else.

Now here they are again, with the reverse of each one:

31 . . . 13      The new number is  18 less.
62 . . . 26      The new number is  36 less.
93 . . . 39      The new number is  54 less.

Obviously, the original number is 62.
