Answer:
C= 6.28 A: 3.14
Step-by-step explanation:
Circumference of a circle is 2* pi * r
Based on this, we can subsitute r for 1
2* pi * 1= 2pi which is around 6.28 units
Area of a circle is pi* r* r
Based on this, we can subsitute r for 1
pi* 1* 1= pi= 3.14 units squared
Since it's 
, move the decimal over 3 places to the right. When you do that the answer should now be 
.
Hope this helps!
