Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we have to find the Diameter of the circle whose Radius is 4 cm.
• So, to find the Diameter, we have to use the formula of :

$\boxed{ \sf Diameter = 2 \times radius }$

• Here, we have to multiply the Radius by 2 to find the Diameter.

Given :

• Radius = 4 cm

To find :

• Diameter

Solution :

We know that,

$\sf Diameter = 2 \times radius$

              $\sf = 2 \times 4$

              $\sf = 8$

Therefore, the Diameter of the Circle with a radius of 4 cm is 8 cm.
