Answer:
A
Step-by-step explanation:
Answer:
50%
Step-by-step explanation:
because 9 is half of 18, and half= 50 or 1/2
B. 7x + 6
Combine like terms. The x terms go together, and nothing changes with the 6 in this expression.
Answer:
- r = √(3V/(πh))
- r ≈ 5.03 feet
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
This formula can be used to find the radius, or we can rearrange it to solve for the radius:
3V = πr²h . . . . multiply by 3
(3V)/(πh) = r . . divide by the coefficient of r²
r = √(3V/(πh)) . . . . take the square root
__
We can fill in the given values to find the radius.
r = √(3·225/(π·8.5)) = √(1350/(17π)) ≈ 5.03 . . . . feet
