The longest chord of a circle is 24 CM. What is the radius of the circle? ​

Answer 1

hey mate

here is your answer

The longest chord in circle is known as its diameter.

Diameter =24cm

Diameter is double of radius

So, radius is 1/2 half of diameter.

Radius = 24/2

Radius =12cm

Answer 2

The longest Chord of the circle is also known as Diameter of a Circle

∴ Diameter = 24 cm

and as we know that

∵ r = $\frac{d}{2}$

⇒ r = $\frac{24}{2}$

∴  r = 12 cm.
