Answer:
12.56
Step-by-step explanation:
How I remember the area formula of a circle is with the word PIZZA. Pizza are you know is a circle and I break down the word. PI= 3.14, ZZ= Z² (but in books and class they will use r², I'm replacing that r with a z), A= area.
Using my formula
PIZZA
Pi=3.14
ZZ= 2²=4
A= area
3.14*4=area
12.56=area
Yes it is a function.
B is my answer.
