Answer:
You could answer this two ways.
Step-by-step explanation:
Method 1: Set up proportion
x/40=55/100
Cross-multiply and you will get..
2200=100x
x=22
Method 2: Use decimals
As we saw in the first method, 55 percent is equal to 55/100. 55/100 is equal to 0.55.
You can multiply 0.55 and 40 to get the answer as well.
0.55 times 40 is 22.

Answer: Doubling the radius.
Step-by-step explanation:
The volume of a cone can be found with the following formula:

Where "r" is the radius and "h" is the height of the cone.
Let's find the volume of the conical tent with a radius of 10.4 feet and a height of 8.4 feet.
Identifiying that:

You get this volume:

If you double the radius, the volume of the conical tent will be:

When you divide both volumes, you get:

Therefore, doubling the radius will quadruple the volume of the tent.
