To solve this, you can use this helpful equation:
= 
Since you now have this equation, you can just plug in.
= 
To find x you would cross multiply, multiply the x with 100 and the 15 with the 20%.
100x = 300
Now to find x you would just divide both sides by 100.
x=3
Answer:
can you take a picture of it
Step-by-step explanation:
Answer:
Volume of the cone = 
Step-by-step explanation:
Volume of a right circular cone:
For, h=3.9 feet
r= 14.7 feet
As, 
Volume :
Volume of the cone is
5(2.7)= 13.5
You just plug in 2.7 for x
15.27 = 15.3
First you look at the hundreths place. Since it is greater than 5 you round up. If it was less than 5 you round down. So 15.27 rounded to the nearest tenth is 15.3
Answer: 15.3
Example: 27.23 = 27.2
32.58 = 32.6
