$2\pi \: r$

r=3cm

π=22/7

Answer 2

Answer :-

• The area of circle is 28.26cm².
• The circumference of circle is 18.84cm.

Step-by-step explanation :

To Find :-

• The area of circle
• The circumference of circle

Solution :-

Given that,

• π = 3.14
• Diameter of circle = 6cm

∴ Radius = Diameter ÷ 2

=> ( 6 ÷ 2 ) cm

=> radius = 3cm.

According the question,

• The area of circle

As we know that,

Area of circle = πr² sq. units,

Where,

• π = 3.14
• r = radius

=> Area = πr²

=> 3.14 × ( 3 )²

=> 3.14 × 3 × 3

=> 3.14 × 9

=> Area = 28.26

• The area of circle is 28.26cm²

Now,

• The circumference of circle

As we know that,

Circumference of circle = 2πr units

Where,

• π = 3.14
• r = radius

=> Circumference = 2πr

=> 2 × 3.14 × 3

=> 3.14 × 6

=> Circumference = 18.84

• The circumference of circle is 18.84cm.
