Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: \frac{1}{3} *b*h

\frac{1}{3} *π*r²*h=

\frac{1}{3} *3.14*15^{2} *60=\\

\frac{1}{3} *3.14*225*60=

\frac{1}{3} *3.14*13,500=\\

\frac{13,500}{3} *3.14=\\

4500*3.14=

14,130 feet³

<u><em>PART A</em></u>

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

<u>So for 2 pounds, it would cost </u><u>$5.00</u>

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

<u>For the 1 pound one, it would cost </u><u>$2.50</u>

<u></u>

<u><em>PART B</em></u>

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, <u>$1 = 0.4lb</u>

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x <u>$9 = 3.6lb</u>

<u></u>
