Question

Circumference of a circle with diameter 1 meter is

(a) 3.14 cm (b) 31.4 cm (c) 314 cm (d) 3140 cm​

Answer 1

3.14 or A

Explanation:

1 . Find the actual circumference of the circle.

The formula for finding the circumference of a circle is :

c = πd OR c = 2πr

In this case, we have the diameter already given to us to we don't need to use the second formula!

NOTE : People will normally use 3.14 instead of the symbol π, so that is how we will find our answer.

2. Plug in the values we know into the formula.

c = 3.14 * 1

c = 3.14

There you go!

Answer 2

C = 3.14 cm

Explanation:

Hi ! Our task is to find the circumference of a circle, given that its diameter is 1 meter.

Applying the formula,

• 
  `\tt{C=\pi d}`

where C = circumference & d = diameter.

I'll use 3.14 for pi. Then:

`\tt{C=3.14*1}`

`\boxed{\pink{\tt{C=3.14\:cm}}}`
