Answer: 6 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone= (1/3) π radius² height
Replacing with the values given and solving for r:
36π = (1/3) π r² 12
36π/ [(1/3) π 12]= r²
9 = r²
√9 =r
3 ft = r
Since:
Diameter = 2 x radius
Substituting r=3
D = 2x 3
D = 6 feet

To solve this problem you must apply the proccedure shown below:
1. First, you must understand the information given in the exercise. You have that: nine less than two-thirds a number is greater than twenty-five.
2. Let's call to the number mentioned above. You have that "nine less than two-thirds a number" means a substraction and " is greater than twenty-five" can be expressed with the symbol >.
Therefore, you have that the answer is:
Answer:
15 sqrt 3.
Step-by-step explanation:
You haven't listed any choices but here's one equivalent:
3 sqrt 75 = 3 * sqrt (3 * 25)
= 3 * sqrt 3 * sqrt 25
= 3 * 5 * sqrt 3
= 15 sqrt 3.
