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
So unfortunate, calculators haven't been invented yet :/

Answer:
The height of Julio greater than the height of Frieda .
Step-by-step explanation:
Given height as :
The height of Frieda = 5 ft
The height of Julio = 5 ft
So, The height of Frieda = 5
= 5 +
=
= feet
∴ The height of Frieda = 5.25 feet
And The height of Julio = 5 ft
So, The height of Julio = 5
= 5 +
=
= feet
∴ The height of Julio = 5.83 feet
Since 5.83 feet 5.25 feet
So the height of Julio the height of Frieda
Hence The height of Julio greater than the height of Frieda . Answer
