Answer:201 in squared

Step-by-step explanation:

a right circular cone has

a diameter d=8+in ...........r=4+in

a height of h=12+in

the volume

the vomue 1/3 times pie times r squared times height

the vlolume 1/3 times pie times 4 in squared times 12in

the vlolume 1/3 times pie times 16 in squared times 12 in

the vlolume 192 times pie inches squared over 3

the vlolume 200.96 in squared

whcih should equal 201 inches squared.

Answer:12.9 inches

Step-by-step explanation:

V=1/3\pi r²

3V=\pi r² h

h=3V/r²\pi

h=3(488)/(6)²\pi

h=1464/36\pi

h=12.9446...

5/4 to 3/8 as a percent change
Digiron [165]
Well, what's the diffrence from 5/4 to 3/8?

\bf \cfrac{5}{4}-\cfrac{3}{8}\qquad \stackrel{\textit{LCD is 8 clearly}}{\implies }\qquad \cfrac{10-3}{8}\implies \cfrac{7}{8}

so, if we take 5/4 to be the 100%, what is 7/8 off of it in percentage anyway?

\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;\frac{5}{4}&100\\\\&#10;\frac{7}{8}&x&#10;\end{array}\implies \cfrac{\quad \frac{5}{4}\quad }{\frac{7}{8}}=\cfrac{100}{x}\implies \cfrac{5}{4}\cdot \cfrac{8}{7}=\cfrac{100}{x}&#10;\\\\\\&#10;\cfrac{40}{28}=\cfrac{100}{x}\implies x=\cfrac{28\cdot 100}{40}
