Using the formula for volume of a cone, express r in terms of V, h and pi
DiKsa [7]

The volume of the cone is one-third of the volume of the cylinder which is equal to the product of area of the base and the height. The equation is,

<span>    V = (1/3)(pi)(r^2)h          </span>

Dividing both sides of the equation by (1/3)(pi)(h) will give us,

<span>  3V/(pi)(h) = r^2</span>

Taking the square-root of both sides,

<span>  r = sqrt(3V/(pi)(h))</span>

Lashonda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.C
musickatia [10]
Answer:
30 < m
The solution would be (30, ∞)

Explanation:
For company A:
The charge is: $96 for any number of mileage ..............> I
For company B:
The charge is $75 fixed and 0.7 for each mileage m. This means that the charge is: 75 + 0.7m .................> II

We want the charge of company A to be less than the charge of company B. This means that we want I to be less than II.
Therefore,
96 < 75 + 0.7m
96 - 75 < 0.7m
21 < 0.7m
21/0.7 < m
30 < m

This means that for any mileage greater than 30, the charge of company A will be less than the charge of company B

Hope this helps :)
