Question

PLEASE HELP

Answer 1

I Dont know what to do

Answer 2

Not the slightest clue?

Answer 3

oh no

Answer 4

Well, what's the formula of a circle?

Answer 5

2 pi r

Answer 6

Wait a sec. I be back

Answer 7

Is that the formula for the area or the circumference.

Answer 8

Hello?

Answer 9

2 pi R is the formula for area

Answer 10

Ok. So just divide the diametre by 2 for the radius, and divide the result you get from the formula by 2 for the semi-circle. The multiply that by 6, cause there's 6 circles.

Answer 11

is that it?

Answer 12

No

Answer 13

That's only for the circles.

Answer 14

For the perimetre, use the formula for a circumference, and divide that by 2, and multiply it by 6. Once you're done that, imagine the polygon in the middle as 6 triangles.

Answer 15

ok so for all the areas for the circles i got 150.79644737231007544620688239742

Answer 16

Ok. Is that for 1 circle, or all 6?

Answer 17

all 6

Answer 18

Ok. Now we need the area of the polygon in the middle.

Answer 19

8 times 6 right

Answer 20

Is there any shape you think we can break up the middle polygon? That you could use to calculate the area?

Answer 21

hexagon so 8 times 6

Answer 22

I dunno. I guess? I didn't do any work on this yet.

Answer 23

ok i got that and aded the area from the circles so i got a wierd number but it rounds up to 199

Answer 24

Very strange. COuld you show your work (Scanning it would make less work i think)

Answer 25

And your perimeter?

Answer 26

AGh. Inches.

Answer 27

8 time 6 and then the area from the circles was 150 (rounded up to 151)

Answer 28

Wats the 8 from?

Answer 29

its the distance of each side of the hexagon

Answer 30

I think you're right. I wouldn't really know.

Answer 31

But if you, who did it, thinks its right, then there must be some truth to it.

Answer 32

The perimeter is the circumference of 3 circles whose diameter is 8. The circumference of 1 circle is pi(diameter) so 3 circles = 3(pi)(8)= 24pi = 75.4

The area of the three circles is 3(pi)(r^2) = 3(pi)(16)= 48pi=150.8
