$\large \tt Answer$

$\colorbox{cyan}{\tt = 2 \: cm}$

Explanation

First of all , understand what diameter actually is well it's the longest chord in a circle touching the circumference from either side now in question

Diameter of the Circle is given i.e 4 cm we have to find the radius, radius is one - half of a diameter touching a circumference from one side and centre of the circle from other side .

We know that ,

$\implies \tt Radius = \dfrac{Diameter}{2}$

$\tt Radius = \cancel \dfrac{4}{2} = 2$

Conclusion

The radius of the circle is 2 cm .

Thankyou

Answer 2

Here, we have

Diameter=4 cm

Since the diameter is known to us,

we can calculate the radius of the circle.

Radius = diameter/2

Radius=2 cm
