Please help me ASAP, thank you ^-^. The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of π?
MrRa [10]
<h2>Answer:</h2>

The volume of the cone in terms of π is:

             

A.     392π in³

<h2>Step-by-step explanation:</h2>

The radius of the cone i.e. r is: 7 in.

and the slant height of the cone i.e. l=y=25 in.

and let h=x be the height of the cone.

Now, using the Pythagorean Theorem we have:

l^2=r^2+h^2\\\\i.e.\\\\h^2=l^2-r^2\\\\i.e.\\\\h^2=(25)^2-7^2\\\\i.e.\\\\h^2=625-49\\\\i.e.\\\\h^2=576\\\\i.e.\\\\h=\sqrt{576}\\\\i.e.\\\\h=24

Hence, we get:

h=x=25\ in.

Now, the volume of the cone is given by:

Volume=\dfrac{1}{3}\pi r^2h\\\\i.e.\\\\Volume=\dfrac{1}{3}\times\pi\times (7)^2\times 24\\\\i.e.\\\\Volume=392\pi\ in^3

        Hence, the answer is: Option: A

Wool Inc. also sells wool so that crafters can use their signature wool to create their own products at home. Wool Inc. produces
MariettaO [177]

a. Wool Inc. should <u>process further</u> Red Wool and Blue Wool.

b. Wool Inc. can sell Blue Wool at the split-off point at <u>$24 per unit </u>($120,000/5,000) without further processing, instead of selling at $36 per unit ($180,000/5,000) after further processing.

<h3>What is the split-off point?</h3>

The split-off point is the processing point when joint products can be further processed separately.

At the split-off point, the costs of the joint products can be identified separately.

<h3>Data and Calculations:</h3>

Sales Value and Additional Costs If Processed Further:

                    Pounds       Sales Value     Final Sales   Further      Profit from

                 Produced       at Split-Off          Value   Processing       Further

                                                                                        Cost       Processing

Red Wool     10,000         $110,000       $200,000    $50,000   $40,000

Blue Wool     5,000          100,000           180,000      60,000     20,000

Yellow Wool 3,000           90,000            110,000       21,000       -1,000

Thus, the profits from further processing are computed as the Final Sales Value minus Further Processing Cost minus Sales Value at the Split-off point.
