Question

diameter of the circle=54
then radius=​

Answer 1

As per the data given in the question,

We have to determine the value of radius of the circle.

As per question,

It is given that,

Diameter of circle = 54 unit

As we know that,

Radius of the circle is the length of line drawn between the centre of circle and the outer boundary of the circle.

While diameter of circle is the length of line drawing from the two ends of borders of circle going from the centre of circle.

So, from here,

We can understand that,

The diameter of circle is double in length as compared to the radius of circle.

So, we can say that,

$Diameter = 2 \times radius$

Hence, radius of circle will be $=\frac{54}{2} = 27\:units$

Hence, radius of circle will be 27 units.

Answer 2

Given: The diameter of the circle is$54$.

We have to find the radius of the circle.

• As we know that the radius of the circle is the length of the line drawn between the centre of the circle and the outer boundary of the circle.
• And the diameter of the circle is the length of the line drawing from the two ends of borders of the circle going from the centre of the circle.

We are solving in the following way:

We know that,

$Diameter=2\times Radius$

We have$D=54$

$\therefore Radius=\frac{D}{2} \\\\=>Radius=\frac{54}{2} \\\\=>Radius=27$

Hence, the radius of the circle will be$27$ units.
