Question

The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below.

V = 3r2h
Write the formula to calculate the height, h.

Answer 1

h = V/3r²

Explanation:

just did the test

Answer 2

V/3r²

Explanation:

We are to make h the subject of the formula as shown;

V = 3r²h

Divide both sides by 3r²

V/3r² = 3r²h/3r²

V/3r² = h

Rearrange

h = V/3r²

Hence the formula to calculate the height h is V/3r²
