Question

Find the area of this circle

Answer 1

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

Answer 2

Area of a circle is pie times the radius to the second power.

So the answer is 4 time pie
