Answer 2

$\huge \frak\color{magenta}{required \: answer:}$

Given :-

• Length of longest chord is 21 cm

To Find

• Radius of the circle

Solution :-

(Longest chord is diameter of the circle.)

Diameter → 21 cm

$\rm \color{blue}{radius = \frac{diameter}{2} = \frac{21}{2} = 10.5cm}$

$\frak \pink{ \therefore radius \: of \: the \: circle \: is \: 10.5 \: cm}$

$\frak \red{points \: to \: remember:-}$

• Circle is a plane figure which is not made of any line segment.

• Radius is a line segment joining the centre of a circle to any point of the circle.

• Chord is a line segment joining any two points of the circle.

• Diameter is a line segment joining any two points of a circle and which passes through the centre of the circle.

• Diameter is the longest chord of the circle.

• Diameter = 2 (radius)
