Answer:

206.17

Key(s):

A = 2\pi \frac{d}{2} h + 2\pi \left(\frac{d}{2}\right)^2

Substitute <em>d</em> for the actual diameter, 7.5, and <em>h</em> for the height, which is 5.

Step-by-step explanation:

A = 2\cdot\pi \cdot\frac{7.5}{2} \cdot5 + 2\cdot\pi \cdot\left(\frac{7.5}{2}\right)^2 ≈ 206.17(2 DP)

Find the missing x value for for question 14
zloy xaker [14]

Answer:

x=12 but who knows maybe

Step-by-step explanation:

if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.

Answer:

  slope = 2

Step-by-step explanation:

See the attachment for the markup.

It is usually convenient to choose places where the graph crosses grid intersections. Here, the graph crosses the x- and y-axes at integer values, so those points could be used, for example. We chose points away from the axes so that the rise and run lines could be seen more easily.

The graph has a rise/run of ...

  slope = rise/run = 2/1 = 2

The slope of the line is 2.
