a container of candy is shaped like a cylinder and has a volume of 125.6 cubic centimeters. If the heights of the container is 1
Elenna [48]

The radius of the container is 2 centimeter

<h3><u>Solution:</u></h3>

Given that a container of candy is shaped like a cylinder

Given that volume = 125.6 cubic centimeters

Height of conatiner = 10 centimeter

To find: radius of the container

We can use volume of cylinder formula and obatin the radius value

<em><u>The volume of cylinder is given as:</u></em>

\text {volume of cylinder }=\pi r^{2} h

Where "r" is the radius of cylinder

"h" is the height of cylinder and \pi is constant has value 3.14

Substituting the values in formula, we get

\begin{array}{l}{125.6=3.14 \times r^{2} \times 10} \\\\ {r^{2}=\frac{125.6}{31.4}} \\\\ {r^{2}=4}\end{array}

Taking square root on both sides,

r = \sqrt{4}\\\\r = 2

Thus the radius of the container is 2 centimeter

Mars2501 [29]

Answer:

Step-by-step explanation:

We know that the break even point is the point where the cost and the revenue equations intersect.  So the break even point in this situation is:

C= R

<=> 20/3x+50 = 10x (with x > 0 and x is a whole number)

<=> 10x^{2} -50x -20 = 0

<=> x ≈ 5

If the company sells more than 5 items, it will have benefit

If the company sells less than 5 items, it will lose

How to find the surface area and volume of a square
3241004551 [841]

Given:

The shape is square.

To find:

The surface area and volume of a square.

Explanation:

The length of each side of the square is "a" units.

The formula for the surface area of the square is,

\begin{gathered} Surface\text{ area = 6}\times Area\text{ of the square} \\ S.A=6a^2\text{ square units} \end{gathered}

The formula for the volume of the square is,

\begin{gathered} Volume,\text{ V= Length }\times breadth\times Height \\ =a\times a\times a\text{ cubic units} \\ V=a^3\text{ }cubic\text{ }units \end{gathered}

Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.

For example:

Let the side length of 3cm for a square.

So, the dimensions are 3cm by 3cm by 3cm.

That is,

The Length is 3cm.

The breadth is 3cm.

The height is 3cm.

So,

a=3cm

The surface area of the square is,

\begin{gathered} S.A=6a^2 \\ =6\left(3\right)^2 \\ =6\times9 \\ =54cm^2 \end{gathered}

Therefore, the surface area of the square is 54 square cm.

The volume of the square is,

\begin{gathered} V=a^3 \\ =3^3 \\ V=27cm^3 \end{gathered}

Therefore, the volume of the square is 27 cubic cm.
