Question

diameter of circle is 8 cm what is the length of its radius​

Answer 1

Hello mate..

Answer:

GIVEN:

• Diameter of circle = 8 cm.

TO FIND:

Radius of the circle

SOLUTION:

$\rightarrow \tt \red{radius \: of \: a \: circle = \frac{diameter(d)}{2} }$

$\rm \implies{ \frac{8}{2} } \\ \rm{ = 4}$

Therefore, radius of a circle is 4 cm when the diameter is 8 cm.

HOPE THIS HELPS YOU..

THANKS..!!

Answer 2

QUESTION :

diameter of circle is 8 cm what is the length of its radius

SOLUTION :

Hint: We had to only divide the diameter of the circle by 2 to get the required radius of that circle because the diameter of the circle is always twice its radius.

• Complete step-by-step answer:

As we know that the diameter of any circle is the line segment passing from the centre of the circle and the endpoint of that line segment lies on the circle. So, there can be many diameters of a circle but the length of all the diameters must be the same.

Now the radius of the circle is the line segment whose one endpoint is at the centre of the circle and the other lies on the circle. And there can also be many such line segments but the length of all of them must be the same.

So, the length of radius of the circle must be half of the length of the diameter of the circle.

Now as given in the question that the diameter of the circle is 8cm.

So, the radius of the circle must be equal to 8/2=4cm
