Question

Determine the delivery radius for your shop. Draw a point on a coordinate plane where your shop will be located. Create two different radii lengths from your shop, and construct the circles that represent each delivery area.

Answer 1

a) How much area will each delivery radius cover?
b) Write the equation for each circle created.

Answer 2

determine a center and a radius and write up the equations: center (a,b), radius r
\[(x-a)^2 + (y-b)^2 = r^2\]

Answer 3

how do I do that again @amistre64

Answer 4

i thought my posts were pretty well self explantory

Answer 5

Okay, but I'm still confused. How do I find the area?

Answer 6

to find the circle's area, use this formula

A = pi*r^2

Answer 7

okay. With what numbers?

Answer 8

this question is asking YOU to pick numbers ... not us.

Answer 9

you need to determine you favorite center point, and your favorite 2 radius lengths ... the rest is just plug and play

Answer 10

I KNOW that much. But HOW do I figure out WHERE to plug them in?

Answer 11

determine a center and a radius and write up the equations: center (a,b), radius r
\[ (x-a)^2 + (y-b)^2 = r^2\]

Answer 12

WHY do you keep typing that equation in!!! I already know that and I asked @jim_thompson5910 to help me. Because your confusing ME!!!

Answer 13

... good luck then

Answer 14

well if you wanted to find the area of a circle with a radius of 6, then you would replace r with 6 in A = pi*r^2

but you can come up with circles of any radius since it says "Create two different radii lengths"

Answer 15

So, if I had the coordinates (3,6), then how would I plug that in?

Answer 16

for the center you mean?

Answer 17

YEA.

Answer 18

if so, then (3,6) = (a,b) as amistre64 is saying

so

a = 3
b = 6

and you plug them into (x-a)^2 + (y-b)^2 = r^2

Answer 19

By the way, @amistre64 I didn't mean it in a rude way. I just need to finish the assignment because I have a deadline and I didn't understand what you were saying
Don't take it offensive

Answer 20

And for the radius, how would I do that. Find the diameter and divide it in half @jim_thompson5910

Answer 21

the radius is something you come up with since it says "Create two different radii lengths..."

Answer 22

so this is where you can be creative

Answer 23

OHHH.... That's why @amistre64 kept saying "Create two different radii lengths?" So. I could choose 7, and that would be my radius

Answer 24

yep, any positive number you want

Answer 25

thank you. I have to create a second circle

Answer 26

np

Answer 27

wait @jim_thompson5910 I was saying. am I supposed to create a second circle?

Answer 28

oh yes, yes you do

Answer 29

im fine :)

Answer 30

just do the same thing, as before @jim_thompson5910 ?

Answer 31

I'm assuming it's from the same center, so just pick a different radius

Answer 32

yes

Answer 33

@amistre64 , okay, because I thought I had offended you and I didn't mean to because I wasn't understanding what you was saying. I do now because it was explained to me. thanks for putting up with my confusion :) :)

Answer 34

thanks, @jim_thompson5910 enjoy ur medal
