Question

Find the circumference of a circle whose radius is 10.5 cm​

Answer 1

Answer:

Circumference of a circle is $66$ cm.    

Step-by-step explanation:

Given : Radius of a circle = $10.5$ cm

To find : The circumference of a circle = ?

Solution :

• It is given that the radius of a circle = $10.5$ cm
• We have to find the circumference of a circle.
• Circle has a set of all points at an equal distance from the center.
• Circumference of a circle is a outer boundary of the circle.
• The formula for circumference of a circle is given by,

       Circumference of a circle = $2\pi r$

                                            = $2*\frac{22}{7} *10.5$

                                            = $2*22*1.5$

                                            = $66$ cm

• ∴ Circumference of a circle is $66$ cm.
