Answer 1

Do you remember the formula of finding the area of a circle?

Answer 2

no >.<

Answer 3

I'm going to give you the formula. Make sure to remember it. \[\large \large r^2 \pi = A\]

Answer 4

Do you know how many radius there is in 1 diameter?

Answer 5

1/2 radius?

Answer 6

Your saying that 1/2 radius is equal to 1 diameter?

Answer 7

i think o_o

Answer 8

Yes?

Answer 9

i have no idea o_o (i just started on this subject >.<)

Answer 10

The First one?

Answer 11

Answer 12

So how many radius is equal to 1 diameter?

Answer 13

Still confused O_O

Answer 14

Here's a great tip: Radius: The distance from the center to the edge of a circle

Answer 15

A= pie times r squared answer: 1. pi times forty-one squared

Answer 16

So how many radius is equal to 1 diameter?

Answer 17

hope it helps :)

Answer 18

You broke 2 rules of the CoC, Mr. >:(

Answer 19

o_o

Answer 20

>.<

Answer 21

Anyway, do you want me to tell you how many radius is equal to 1 diameter?

Answer 22

yes please c;

Answer 23

A= pie times r squared answer: 1. pi times forty-one squared <---- THE ANSWER

Answer 24

Okay. So 2 radii is equal to 1 diameter.

Answer 25

And no, that's not the answer.

Answer 26

:)

Answer 27
