Question :
Cone is formed from 3200 ft³ of gravel, if the height of the cone is 24 ft what is the radius in feet of the base of the cone
Answer:
11.3 feet
Step-by-step explanation:
The volume of a cone = πr²h/3
We are asked to find the radius
The formula is given as:
r = √3V/πh
V = 3200 ft³
h = 24 ft
r = √3 × 2400/π × 24
r = 11.28379 ft
Approximately = 11.3 ft
The radius in feet = 11.3 ft
Answer:
A. 8/5
Step-by-step explanation:
If the G is equal to 8 then the fraction would have to be 8 over ___. 2+3 is 5 so the answer is A. 8/5.
I would say it is 4 because that is really the only one to make much sense <span />
<u>Choice A: </u>
<u />
<u>Choice B: </u>9, 40, 41
<u>Choice C: </u>
Answer:
(B)9, 40, 41
Step-by-step explanation:
To check if the sides form a right triangle, you check to see if they satisfy the Pythagorean theorem.

Note that the longest side length is always the hypotenuse.
<u>Choice A: </u>
<u />
Now, 
Therefore:

These side lengths form an equilateral triangle. They do not satisfy the theorem.
<u>Choice B: </u>9, 40, 41
The longest side length is 41.


Therefore:

These side lengths form a right triangle.
<u>Choice C: </u>

Therefore, the longest side length is 

These side lengths do not form a right triangle.
