Find the volume of the cylinder. Use 3.14 for

dexar [7]

Answer:

volume = 16956 meters

Step-by-step explanation:

volume = area * height

= pi * r^2 * height

= 3.14 * (30m/2)^2 * 27

volume = 16956 meters

Find the volume of the tank below. A. 63 m^3 B. 54 m^3 C. 78 m^3 D. 96 m^3

Andrei [34K]

Answer:

$V = 62.832m^3$ (Approximation to the nearest thousandth)

Step-by-step explanation:

The area of a cylinder can be determined by the formula:

$V = \pi r^2h$ (We know that the radius, r, is 2m, and the height, h, is 5m, so we can substitute them into the formula to calculate the volume of this cylindrical tank)

$V = \pi * 2^2 * 5$ (Simplify)

$V = 20\pi$

$V = 62.832m^3$ (Approximation to the nearest thousandth)

What is x if n≠m? Please help!

lorasvet [3.4K]

Answer: $x = \frac{mn(q - p)}{n-m}\\\\$

================================================

Work Shown:

Part 1

$\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\$

Part 2

$\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\$

-------------------------------

Explanations:

There are quite a bit of steps. I decided to break things into two parts.
The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.
Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.
From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).
The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.

Ramen purchase a box of candy for himself on the way back to the dorm he ate 2/3 of the candy while he was putting away grocerie

Aleksandr [31]

Answer:

12 chocolates

Step-by-step explanation:

Represent the original number of chocolates by c.

Then (1/4)(2/3)c = 2

Solving this for c, we multiply both sides by 4: (2/3)c = 8

and then multiply both sides by (3/2): c = (3/2)(8) = 12

Originally the box contained 12 chocolates.

Find the missing side of the missing side. The length of the missing side is: ?m

WARRIOR [948]

Your answer is 76m.

a^2+b^2=c^2

57^2+b^2=95^2

3249+b^2=9025

b^2=5776

Take sqr on both sides and you get:

b=76m
