The volume of a cone, V, is represented by , where r is the cone’s radius and h its height.

Arlecino [84]

So the height will equal 95.50 inches.

So if you double the height the volume is 1800cm3 and that is double the original volume

And if you double the height the volume is 3600cm3 and that is the triple the original volume

What percent of 99 is 90?

Yuri [45]

Answer:

91%

Step-by-step explanation:

We can use the formula $\frac{is}{of}=\frac{percent}{100}$

"is" is 90
"of" is 99
"percent" is what we are solving for so we will denote it as x

Substituting in our values we get $\frac{90}{99}=\frac{x}{100}$

We will need to cross multiply here to get (90)(100) = (x%)(99)
This simplifies to 9000 = 99x%
Dividing by 99 on both sides we get 90.9% → x = 91%
