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

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

Write the formula to calculate the height, h.
h=

Formula for height of cone (h) = 3 V / [(π)r²]

Step-by-step explanation:

Given:

V = 1/3(π)r²h

Find:

Formula for height of cone

Computation:

V = 1/3(π)r²h

3 V = (π)r²h

3 V / [(π)r²] = h

Formula for height of cone (h) = 3 V / [(π)r²]

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
