These cones are similar. Find the volume<br>of the smaller cone. Round to the<br>nearest tenth.<br>

sattari [20]

Answer:

Step-by-step explanation:

If the two cone are similar then the heights are the same

let us find the height of the bigger cone

$volume of cone= \frac{1}{3} \pi r^2h$

For the bigger cone

r= 3cm

v= 66cm^3

$66=\frac{1}{3}*3.142*3^2*h\\ 66=\frac{28.278}{3} *h\\h*28.278=198\\h=\frac{198}{28.278} =7cm$

For the smaller cone

r=2cm

v=?

h=7cm

$v=\frac{1}{3}*3.142*2^2*7\\\v=\frac{87.976}{3} \\\\\v=29.30cm^3$

One number is 1/4 of another number. The sum of the two numbers is 5. Find the two numbers. Use a comma to separate your answer

masha68 [24]

Answer: 1, 4

Step-by-step explanation:

Number #1 = x
Number #2 = $\frac{1}{4} x$

$\frac{1}{4} x+x=5\\\\\frac{1}{4} x+\frac{4}{4} x=5\\\\\frac{5}{4} x=5\\\\5x=4*5\\5x=20\\x=4$

Number #1 = x = 4
Number #2 = $\frac{1}{4} x$ = $\frac{1}{4} *4=\frac{4}{4} =1$
