Question

Help me.

Answer 1

Question here.

Answer 2

Ok so the formula for circumference of a circle is\[2 \pi r=C\]
So you can substitute\[2 \pi r=36 \pi\]
Solve for r

Answer 3

Then when you get r you can put that into the formula for area of a circle which is\[A=\pi r^2\] and simplify for the area

Answer 4

@Directrix

Answer 5

He told you how do it, the circumference=2pir so what is C?

Answer 6

im not sure lol

Answer 7

What is the circumference?

Answer 8

Well get the r by itself @TylerMckinney16, divide 36pi by 2pi to get r

Answer 9

And then substitute into the area formula

Answer 10

Do you need to find area? I didn't see that part?

Answer 11

What is 36pi/2pi?

Answer 12

Yes the question asks for area
Also it's best if you figure out that part for yourself, that is essential algebra

Answer 13

18

Answer 14

Yes now plug that into the formula pir^2

Answer 15

(18-r)

Answer 16

No

Answer 17

how do i do it lol?

Answer 18

It's the equation pir^2

Answer 19

81(pi)???

Answer 20

:/ r^r2 so r times r

Answer 21

What's your r that you just found?

Answer 22

18*18=324

Answer 23

Yes

Answer 24

ok lol now what.

Answer 25

You can figure it out :)

Answer 26

You can do it :)

Answer 27

is it the answer lol?

Answer 28

Don't forget the pi

Answer 29

what u mean

Answer 30

Don't forget the pi, it's part of the equation pir^2

Answer 31

so i do 324*3.14?

Answer 32

You can leave pi you don't need to do that I don't think

Answer 33

But did i still leave it set up right?

Answer 34

@kayders1997

Answer 35

So 324pi

Answer 36

And thats right?
