How do you find the volume of a cylinder?? Step by step by step

Answers

Answer 1

Answer:
1). Recall the formula for the volume of a cylinder:

Volume = (pi) x (radius of the round end)² x (length or height) .

2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.

3). Write each number into its place in the formula.

4). Perform the indicated operations. The final number is the
volume of your cylinder.

Answer 2

Answer: the formula is $\pi r^2h$ r= radius
h= height
you square the radius and then multiply by the $\pi$ and then the height

Answer:

Following solution will help you:

Answer:

2x/3 + 2 = y

Step-by-step explanation:

2x - 3y = -6

2x - (-6) = 3y

2x+6=3y

2x/3 + 6/3 = 3y/3

2x/3 + 2 = y

So we're looking at two rectangles, one cut out of the other, so all you do is find the area of the big one, base times height equals area, minus the area of the small one, base times height equals area. So the equation you have to solve for is this,

Area=(12.6X14)-(3X8.4)

The area of a rectangle is 4.9 square units. The length is 2.5 units and the width is y units. Which statements are true? Select each correct answer. A. 2.5y=4.9 B. y=1.96 C. 4.9x=2.5 D. y=12.25

Answers

The answer is A because the area is all the points added together so you need to times it by Y and you get the area which is 4.9

A and B. A is xy=A (4.9) : 2.5*y=4.9 and B is A/x=y so 4,9/2,5=1,96 which is correct

Maria walked 3 km west and 4 km south . calculate how far she is from her starting point.

Answers

if you draw her track and connect her starting and ending points, you have a right triangle, with 3 and 4 being the legs. According to the pythagorean theorem. 3^2+4^2=x^2 when x is her distance from starting point. so x^2=25 and x=5. Her distance is 5
