Question

Diametre of circle whose radious is 7 cm is

Answer 1

• As per the data given in the answer, we have to find the diameter of the circle.

       Given data- Radius= 7cm.

       To find- the diameter of the circle(d)=?

       Solution:-

• We know, the Diameter formula: The diameter formula of a circle is twice its radius. Diameter = 2 × Radius.

        $\Rightarrow D=2r\\\Rightarrow D=2\times7=14cm.$

      Hence, the diameter will be $14cm.$

       

Answer 2

Given that:- Radius $= 7cm$

To find:- the diameter of the circle.

As we know that,

The diameter of a circle is twice its radius.

i.e Diameter $=2\times$ radius

By putting given value in the above formula,

$=>2\times7\\=>14cm$

Hence,  The diameter will be $14cm.$
