\huge\underline{ \sf \: Formulae \: to \: remember \: for \: solving \: the \: question:}


\\{ \sf radius \: of \: a \: circle = (d)/(2) where \: d \: is \: the \: diameter \: of \: the \: circle}


\huge\underline{\sf Given:}


\ \: { \sf The \: diameter \: of \: a \: circle \: is \: 5 mm.}


\huge\underline{\sf To \: find \: out:}


\ { \sf Radius \: of \: the \: circle}


\huge\underline{\sf Solution:}


\\{ \sf The \: diameter \: of \: the \: circle \: is \: 5 \: mm.}


\\{ \sf Therefore \: radius \: of \: the \: circle}


\\{ \sf = (5)/(2) \: mm}


\\{ \sf = 2.5 \: mm}


\huge\underline{\sf Answer:}


\\{\sf The \: radius \: of \: the \: circle \: is \: 2.5 \: mm.}
