Question

If the length of the longest chord in a circle with Centre o is 10 cm
what is the radius of the circle

Answer 1

longest chord in the cicle=diameter
diameter=10cm
radius=diameter/2
=10/2
=5
radius=5cm

hope it helps!

Answer 2

Answer:

The radius is 5 cm

Step-by-step explanation:

Given the length of longest chord in a circle with centre O is 10 cm.

we have to find the radius of circle.

As we know the the longest chord of circle is known as diameter i.e diameter is given which is

Longest chord=Diameter=10 cm

Radius of circle is half of the diameter of circle.

i.e

$Radius=\frac{Diameter}{2}=\frac{10}{2}=5cm$

Hence, the radius of circle is 5cm.
