Question

Given that the diameter of a circle is 5 mm, find the radius of the circle.

Answer 1

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

$\\{ \sf radius \: of \: a \: circle = \frac{d}{2} where \: d \: is \: the \: diameter \: of \: the \: circle}$

$\huge\underline{\sf Given:}$

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

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

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

$\huge\underline{\sf Solution:}$

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

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

$\\{ \sf = \frac{5}{2} \: mm}$

$\\{ \sf = 2.5 \: mm}$

$\huge\underline{\sf Answer:}$

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