1.what is the volume of the small cone in terms of pi

svp [43]

Step-by-step explanation:

Step 1: Find the radius of the big cone

$\frac{radius_1}{height_1} = \frac{radius_2}{height_2}$

$\frac{2}{5}=\frac{x}{10}$

$2(10)=5(x)$

$20/ 5=5x / 5$

$4=x$

Step 2: Find the volume of the small cone

$V = \frac{\pi*r^2*h} {3}$

$V = \frac{\pi * 2^2 * 5}{3}$

$V = \frac{20\pi}{3}\ units^3$ ← Volume of Small Cone

Step 3: Find the volume of the large cone

$V = \frac{\pi*r^2*h} {3}$

$V=\frac{\pi*4^2*10}{3}$

$V = \frac{160\pi}{3}\ units^3$ ← Volume of Large Cone

here is what i got, i hope it helps!

Pail=4 glasses

Jug=3 glasses

Glass=1 glass

4+3+1=8glasses

24L÷8glasses= 3L in each glass

pail=12L (4×3)

jug=9L (3x3)

glass=3L (1×3)

12L+9L+3L=24L

Multiply the numerator and denominator by 7×2 = 14 to eliminate the denominators of those fractions:

$\dfrac{\dfrac37}{\dfrac{7\sqrt{10}}2}\times\dfrac{14}{14}=\dfrac{3\times2}{7\sqrt{10}\times7}=\dfrac6{49\sqrt{10}}$

Rationalize the denominator by multiplying both numerator and denominator by √10:

$\dfrac6{49\sqrt{10}}\times\dfrac{\sqrt{10}}{\sqrt{10}}=\dfrac{6\sqrt{10}}{49(\sqrt{10})^2}=\dfrac{6\sqrt{10}}{49\times10}=\dfrac{6\sqrt{10}}{490}$

Lastly, cancel the common factor of 2 in both the numerator and denominator (which comes from 6 = 2×3 and 490 = 2×245):

$\dfrac{6\sqrt{10}}{490}=\dfrac{3\sqrt{10}}{245}}$
