Question

Calculate the diameter of a circle whose radius is 4.3 centimeter.

Answer 1

Answer:

The diameter of a circle is $8.6$ cm.

Step-by-step explanation:

Given : Radius of a circle = $4.3$ cm

To find : Diameter of the circle.

Solution :

• It is given that the radius of a circle = $4.3$ cm
• We have to find the diameter of a circle.
• Diameter of a circle passes through the center and divides the circle into two half circles.
• Diameter is twice the radius.

       Diameter = $2*Radius$

                     = $2*4.3$

                     = $8.6$ cm

• ∴ The diameter of a circle is $8.6$ cm.

Answer 2

To find : diameter of circle .

Given : radius of circle is $4.3$ cm .

Solution :

• As per given data we know that  radius of circle is $4.3$ cm . We have to find diameter of circle .
• We know that diameter of circle is the straight line passing through center of a circle . It is the twice the length of radius .
• Diameter = $2$ radius  
• Diameter = $2 \times 4.3$

                        $= 8.6\ cm$

Hence , diameter of circle is $8.6\ cm$.
