Question

Find the radius of the circle, where the diameter of the circle is $27cm?$

Answer 1

Finding the radius of the circle

Diameter is the chord passing through the centre of the circle, diameter is twice the radius of the circle.

So, radius is half of the diameter.

$Diameter=2\times radius$

$radius=diameter÷2$

$=27÷2$ $(diameter=27cmgiven)$

$=13.5cm$

Hence, the radius of the circle is $\mathbf{13}\mathbf{.}\mathbf{5}\mathit{c}\mathit{m}$.
