Question

help me with this problem!

Answer 1

Do you know how to find the area of a circle?

Answer 2

A=πr^2?

Answer 3

cool stuff

Answer 4

you have two circles here
find the area of both

Answer 5

the area of the circle with radius 18 yd is ?
the area of the circle with radius 15 yd is?

Answer 6

Taking that bigger area and subtracting that smaller area will give you the area of the path there.

Answer 7

area of the circle with 15 yd radius = 804

area of the circle with 18 yd radius = 1018

Answer 8

so, 1018 - 804 = 214

Answer 9

214 is the area of the path, right?

Answer 10

I think something is wrong with your first area

Answer 11

the 1018 checks out

Answer 12

but the 804 doesn't

Answer 13

my bad, it's 707!

Answer 14

so subtracting them, it's 311.

Answer 15

ok sounds cool

Answer 16

now we want to see how many bags we will need to fill that 311 yd^2 in

Answer 17

how do i do that?

Answer 18

we want to see many bags we will need
so we are going to divide by 311 by 4
and round up since we will need to cover that fractional part with a bag even if we don't use the full bag

Answer 19

8 bags?

Answer 20

311/4 =?

Answer 21

78*

Answer 22

oops

Answer 23

ok good

Answer 24

lol

Answer 25

so that's my answer?

Answer 26

i'm going to need more help with a few questions, could you possibly help me?

Answer 27

yep you will need 78 bags of sand to cover that path
77 will almost do it but you would have a little part of the path that won't get covered
so that is why we need 78

Answer 28

okay, cool

Answer 29

one more I think I can help with
