Marta is solving the equation S = 2πrh + 2πr^2 for h. Which should be the result?
olga_2 [115]

Answer:

h = \frac{S}{2πr} - r


Step-by-step explanation:

The question requires you to make h the subject of the formula.

S = 2πrh + 2πr²

subtract 2πr² on both sides.

S - 2πr² = 2πrh - 2πr² -  2πr²

S - 2πr² = 2πrh

Dividing both sides by  2πr

(S -  2πr²)/2πr =  2πrh/ 2πr

h = \frac{S}{2πr} - r

DiKsa [7]
Simplest way to do this:
 number of books= 120
 percentage represented by 120= 100%
 increase current percent by 55%= 155%

: . 55% increase = original number of books * (155%)
                           = 120 * (155/100)
                           = 186
