Question

Rearrange the variables to write the equation, V = 7.2h, to solve for height, h, as a function of the radius and volume, r and V.

A) h = V / (7.2 * r)
B) h = V / (r * 7.2)
C) h = r * V / 7.2
D) h = r / (7.2 * V)

Answer 1

To solve for height, h, as a function of the radius, r, and volume, V, in the equation V = 7.2h, rearrange the equation to get h on one side and substitute the known values for r and V into the equation. The correct rearrangement of the equation is h = V / (7.2 * r).

Step-by-step explanation:

To solve for height, h, as a function of the radius, r, and volume, V, in the equation V = 7.2h:

1. Rearrange the equation to get h on one side:
2. V = 7.2h becomes h = V / 7.2.
3. Substitute the known values for r and V into the equation:
4. h = V / 7.2 becomes h = V / (7.2 * r).

Thus, the correct rearrangement of the equation is

h = V / (7.2 * r)

To solve for height, h, as a function of the radius, r, and volume, V, in the equation V = 7.2h, rearrange the equation to get h on one side and substitute the known values for r and V into the equation. The correct rearrangement of the equation is h = V / (7.2 * r).
