Question

Can you help me find the arc length of a pizza with 10 slices and diameter of 12”? Here’s the interior angle:

Interior angle = 360°/10 = 36°

And this is what I've got so far, what do i do next..
Arc length = 36°/360°(π•10)
Arc length = 0.1 (π • 10)

Answer 1

is this just you search the circular of pizza the divide into 10?

Answer 2

huh..?

Answer 3

diameter, d= 12 , so it would be Arc length = 36°/360°(π•12)
isn't it ?

Answer 4

@hartnn i was actually just about you ask you to help me, and now i see you're viewing this haha Arc length = 0.1 (π • 10) = ___

for the other question it was Arc length = 0.0833333333333333 (π • 12) = 3.1414 inch

but i don't know how you got that

Answer 5

and i thought it would be (π•10) because it's 10 slices now

Answer 6

Arc length = a/360°(πd)
d is the diameter = 12

Answer 7

circumference divided by slices :)

Answer 8

as long as all the slices are the same size

Answer 9

i see the OS is shuffling the posts :/

Answer 10

even i do .... :/

Answer 11

wait so did i do something wrong? eek

Answer 12

u know this formula , right ?
Arc length = a/360°(πd)

Answer 13

u put a= 36, d=12
and u ar e done

Answer 14

Arc length = 0.1 (π • 12)

Answer 15

But when I said my pizza had 12 slices and was 12” in diameter the arc length was 0.0833333333333333 (π • 12) = 3.1414 inch
So now it’s 10 slices and still the whole thing is 12” in diameter so the arc length is
Arc length = 0.1 (π • 10) = ________

i'm just so confused

Answer 16

d is diameter, not the number of slices

Answer 17

OH okay hahaha so what do i write instead then?

Answer 18

Arc length = 36°/360°(π•12)
Arc length = 0.1 (π • 12)= 3.7399 inch

Answer 19

you are a god omg

Answer 20

thank you SO MUCH YOU HAVE HELPED ME OUT LIKE CRAZY

Answer 21

i assume u meant 'good'
welcome ^_^

Answer 22

haha
