Answer:

<h2>2</h2>

Step-by-step explanation:

\text{If}\ a_1,\ a_2,\ a_3,\ a_4,\ ...\ ,\ a_n\ \text{is a geometric series, then}\\\\\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=\dfrac{a_4}{a_3}=...=\dfrac{a_n}{a_{n-1}}=r=constant

\text{We have}\ 0.75,\ 1.5,\ 3,\ 6,\ ...\\\\\text{The common ratio}\ r:\\\\\dfrac{1.5}{0.75}=2\\\\\dfrac{3}{1.5}=2\\\\\dfrac{6}{3}=2\\\\\boxed{r=2}

Answer:

V=90

Step-by-step explanation:

<u>Step 1:  Find the volume of the cone</u>

<u />V = \frac{\pi *r^{2}*h}{3}

<u>Plug in the values</u>

<u />V = \frac{\pi *3^{2}*10}{3}

<u>Simplify and Solve</u>

<u />V = \frac{\pi *9*10}{3}

V = \frac{90\pi }{3}

V = \frac{90*3 }{3}

V=90

Answer:  V=90
