Question

diameter is 14 cm for find out the circumference of the following circles​

Answer 1

Answer:

44cm2

Step-by-step explanation:

Radius:- 14/2=7

Circumference of circle= 2πr

2×22/7×7= 44cm2

Hence the circumference is 44cm2

Answer 2

• As per the data given in the question, we have to find the value of the expression.

            Given data:- Diameter of circle is $14\ cm.$

            To find:- Circumference of the circle.

            Solution:-

• We know that the Radius is half of the diameter.
• According to the formula,

        $Circumference\ of\ circle=$ $2\pi r.$

    Therefore we have diameter =$14\ cm.$

       so that radius is $7\ cm.$

         $c=2\pi 7\\c=2\times\frac{22}{7}\times7\\c=44.$

Hence we will get the circumference of a circle is $44cm.$
