Question

Make h the subject of the formula A = 2tr (r + h)

Answer 1

h = (A/2tr)

Explanation:

To solve this equation you must still use PEMDAS: Parenthesis, Exponents, Multiplication, Addition, and Subtraction.

Here you have A = 2tr (r + h)

So...

A = 2tr (r + h) divided by 2tr gives us A over 2tr = r + h

Finally we'll subtract r from both sides as well

Answer: (A/2tr) - r = h or h = (A/2tr)

Answer 2

h=(A/2tr)-r

Explanation:

A=2tr(r+h)

A/2tr=r+h

h=(A/2tr)-r
