Question

the circumference of a circle with radius 7 cm is ?​

Answer 1

Answer:

44cm

Step-by-step explanation:

Radius of the circle (r) = 7cm

Formula of Circumference = 2πr          (π =$\frac{22}{7}$ or approximately 3.14)

                                            = $2$ × $\frac{22}{7}$ × $7$

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

                                            = 22 × 2

                                            = 44cm

Answer 2

Answer :

• The circumference of a circle is 44cm

Given:

• The circumference of a circle with radius 7cm is

To find :

• Circumference of a circle

Solution :

Given that,

• Radius of circle is 7cm

As we know that ,

• Circumference of a circle = 2πr

Where r is radius 7cm

⇢ 2πr

⇢ 2 × 22/7 × 7

⇢ 2 × 22

⇢ 44 cm

Hence, The circumference of a circle is 44cm

More Explanation:

• Circumference of a circle = 2πr
• Perimeter of a circle = 2πr
• Area of circle = πr²
• Perimeter of semi circle = πr + 2r
• Area of semi circle = πr²/2
• Circumference is nothing but the distance around the circle
