Question

H=D^2N/2.5, solve for D

Answer 1

The correct answer is:

D=
`\sqrt{(2.5 h)/(N) ]`

Explanation:

We have the equation

h = D^2N /2.5 (1)

We have to clear the equation for (1). Multiplying (1) by 2.5

2.5 h = D^2 N (2)

Dividing (2) by N,

`(2.5 h)/(N)` = D^2 (3)

By taking the square root of (3), finally we have

`\sqrt{(2.5 h)/(N) ]` = D
