Consider the following formula used to find the volume of a cone.

To get rid of the denominator, you have to multiply each side by three, which leaves πr^2 h = 3V, then to get h alone, you need to divide by πr^2 (Since that's being multiplied by h, you wouldn't subtract), so the end equation would be B.

<h2>Answer:</h2>

Option: B is the correct answer.

The formula that can be used to find the height of the cone is:

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

<h2>Step-by-step explanation:</h2>

The formula for finding the volume of a cone is given by:

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

where r is the radius of the base of the cone and h is the height of the cone.

Now in order to find the height of the cone we need to express h in terms of r and V.

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

Hence, the formula is:

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

If you get $2,000 for graduation gifts and invest it in an account that earns 1.5% interest

Eduardwww [97]

Answer:

It is VERY important to use the attached formula.

Years = ln (Total / Principal) / rate

Years = ln (6,000 / 2,000) / rate

Years = ln (3) / rate

Years = 1.0986122887 / .015

Years = 73.24 years

This takes a LONG time because the interest rate is extremely low.

allen is mixing red and yellow paint to make two different shades of orange. to make 1 cup of dark orange paint he needs 7 ounce

slavikrds [6]

Answer:

42 ounces of yellow paint.

Step-by-step explanation:

To make three cups of dark orange, you just need to remember that to make one cup you need: 7 ounces of red paint and 1 ounce of yellow paint. Then, to make three cups, we just have to multiply these proportions by three,which means 7x3 ounces of red paint =21 ounces of red paint, plus 3x1 ounces of yellow paint =3 ounces of yellow paint. Then we need 21 ounces of red paint and 3 of yellow paint to make three cups of dark orange.

To make one cup of light orange, we need 13 ounces of yellow paint, and 3 ounces of red paint. Then, to make three cups, we just multiply this proportion by 3, as follows: 13x3 ounces of yellow paint = 39; and 3x3 ounces of red paint =9. Then we need 9 ounces of red paint and 39 of yellow paint to make three cups of light orange.
Adding up the amount of ounces we need to make dark orange and light orange, we get a total amount of 21+9=30 ounces of red paint and 3+39=42 ounces of yellow paint to make three cups of light orange and three cups of dark orange.
