Question

the diameter of a circle is 24cm find its radius​

Answer 1

Answer:

∴ Radius of a circle is $12$ cm.

Step-by-step explanation:

• In context with question asked,
• We have to find the radius of a circle.
• Given, diameter of a circle = $24$ cm
• We know that, circle is a set of points arranged at an equal distance from the center of a circle.
• Diameter is the longest chord of the circle.
• It is twice the radius.
• So,

     Radius of a circle = $\frac{diameter}{2}$

                               = $\frac{24}{2}$

                               = $12$ cm

• ∴ Radius of a circle is $12$ cm.

Answer 2

Answer:

Hence the value of the radius of a circle is 12 cm.

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The diameter of a circle (d) is 24 cm.

We have to find the value of the radius of a circle i.e.(r).

We know that the radius of a circle is half of the diameter.

Here we will be using the formula of radius as below.

$r=\frac{1}{2} \times d$

We will substitute the value of diameter (d) in the above formula.

Further, we get

$r=\frac{1}{2}\times24$

We will divide 24 by 2

Further, we get

$r=1\times12\\r=12\;cm$

Hence the value of the radius of a circle is 12 cm.
