Question

WHAT IS S=2PIR^2+2PIRH SOLVE FOR H

Answer 1

`\\~\qquad\quad S\ =\ 2PIR^2+2PIRH\\\underline{-2PIR^2\qquad-2PIR^2\qquad\quad\ }\\\\ S-2PIR^2=2PIRH\\\\ 2PIRH\ =\ S-2PIR^2\\\underline{ :(2PIR)\qquad :(2PIR)}\\\\\\ H=(S-2PIR^2)/(2PIR)\\\\\\ H=(S)/(2PIR)-(2PIR^2)/(2PIR)\\\\\\ H=(S)/(2PIR)-R`


or:


`\\~\qquad\quad S\ =\ 2PIR^2+2PIRH\\\\~\qquad\quad S\ =\ 2PIR(R+H)\\\underline{:(2PIR)\qquad :(2PIR)}\\\\\\~\ \ (S)/(2PIR)\ =\ R+H\\\\\\ (S)/(2PIR)-R=H\\\\\\ H=(S)/(2PIR)-R`
