Answer 2

Question :

if the length of a chord passing through the centre of the circle is 15 CM, what is the radius of the circle?

Answer :

Note :

The cord passing through the centre of the circle is diameter .

$\sf\pink{Given}$

• diameter = 2 × radius

• diameter is 15 cm

Radius =${\dfrac{1}{2}\times diameter }$

$\longrightarrow\bf{\dfrac{1}{2}\times 15 }$

$\longrightarrow\bf\pink{7.5}$

• Therefore the radius is 7.5 cm
