Respuesta :

so we know the formula for circumference is C= πrd. And Circumference is the distance around a circle. 

Example: C= circumference 
C= 6.28 can u find the  circles area :? 
 Step 1: divide 6.28 by 3.14 as the formula says.

Step 2 : after u divided u get 2 which is the diameter. and u divide the diameter by 2 because we are trying to get the radius because the formula for the circles area is 
A= πr ^2

r = radius 
r= 1 

so what is 3.14 times 1
= 3.14

so 3.14 is the answer 

I hope this helped u understand. 

Answer:

Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.
