Answer:

Approximately the volume of cone-shaped container is <u>393 in³</u>.

Step-by-step explanation:

Given:

A company makes a cone-shaped container with a height of 15 in.

The area of its base is about 78.8 in².

Now, to get the cone-shaped container volume.

So, we find the radius first by using formula:

Let the radius be r.

<u><em>(Using the value π = 3.14)</em></u>

A_{B}=78.8\ in^2.

A_{B}=\pi r^2

78.8=3.14\times r^2

<em>Dividing both sides by 3.14 we get:</em>

<em />25.09=r^2<em />

<em>Using square root on both sides we get:</em>

5.00=r

r=5\ in.

Thus, the radius (r) = 5 in.

<u>The height (</u>h<u>) = 15 in.</u>

Now, to get the volume of the cone-shaped container we put formula:

Volume=\pi r^2\frac{h}{3}

Volume=3.14\times 5^2\times \frac{15}{3} \\\\Volume=3.14\times 25\times 5\\\\Volume=392.50\ in^3.

Therefore, approximately the volume of the cone-shaped container is 393 in³.

faltersainse [42]

Answer:

\huge \: t =  \frac{13}{2}

Step-by-step explanation:

10t - 5 = 60

Using the addition property add 5 to both sides of the equation

That's

10t - 5 + 5 = 60 + 5 \\ 10t = 65

<u>Divide both sides by 10</u>

\frac{10t}{10}  =  \frac{65}{10}  \\  t =  \frac{65}{10}

<u>Reduce the fraction with 5</u>

We have the final answer as

t =  \frac{13}{2}  \\

Hope this helps you
