The formula for calculating the volume of a cone is solve this formula for h

elixir [45]

Answer:

$V = \frac{1}{3} \pi {r}^{2} h \\$

multiply either sides by 3:

$3 \times V = ( \frac{1}{3} \pi {r}^{2} h) \times 3 \\ \\ 3V = \pi {r}^{2} h$

divide either sides by πr² :

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

Express in the form n:1 give n as a decimal 21:12

Makovka662 [10]

$1.75:1$ which is similar to n:1 where $n=1.75$

<u>Step-by-step explanation:</u>

Here we have to Express in the form n:1 give n as a decimal 21:12 . Let's find out:

Given ratio as 21:12 . Let's convert it into n:1 , where n is decimal

⇒ $21:12$

⇒ $\frac{21}{12}$

⇒ $\frac{3(7)}{3(4)}$

⇒ $\frac{7}{4}$

⇒ $\frac{\frac{7}{4}}{\frac{4}{4}}$ { dividing denominator & numerator by 4 }

⇒ $\frac{\frac{7}{4}}{1}$

⇒ $\frac{1.75}{1}$

⇒ $1.75:1$ which is similar to n:1 where $n=1.75$

Linda had been collecting stamps for 5 weeks and had 25 stamps in her stamp book. Her book holds 64 stamps. She then began purch

coldgirl [10]

25 divided by 5 is 5 so she gave 5 stamps each week
64 divide by 3 would roughly be 12 weeks because otherwise it would be a renainder
12 add 5 equals 17 weeks
So it should take 17 weeks
hope this is right Please ask me if any doubts
Thank you Good Luck
