\large\underline\mathfrak{GIVEN,}

\dashrightarrow \blue{kx+2y=6}

\dashrightarrow \blue{x=-1}

\dashrightarrow  \blue{y=2}

\large\underline\mathfrak{\red{TO\:FIND,}}

\dashrightarrow \blue{The\:value\:of\:k}

\large\underline\bold{\pink{\mathfrak{SOLUTION,}}}

\implies \green{kx+2y=6}

\therefore \orange{putting\:the\:value\:of\:x\:and\:y\:.}

\implies \purple{k(-1)+2(2)=6}

\implies \purple{-k+4=6}

\implies \purple{-k=6-4}

\implies \purple{-k=2}

\implies \purple{k=-2}

\rm{\boxed{\bf{\circ\:\: k=-2\:\: \circ }}}

\large\underline\mathfrak{THE\:VALUE\:OF\:k\:IS\:-2}

Answer:

Radius of the roller (r)=

2

84

cm=42cm

length of the roller (h)=120cm
