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

1 answer:

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

The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?

Katarina [22]

Answer:

10%

Step-by-step explanation:

We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.

We will use markup % formula for our given problem.

$\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100$

$\text{Markup percentage}=\frac{429-390}{390}\times 100$

$\text{Markup percentage}=\frac{39}{390}\times 100$

$\text{Markup percentage}=\frac{1}{10}\times 100$

$\text{Markup percentage}=10$

Therefore, markup is 10% of cost.
