Question

Can someone please tell me how to find the area of one slice of pizza if my pizza is 12” in diameter and has 12 slices?

Answer 1

can u find area of circle when diameter is given ?

Answer 2

I just don't know what to do, no.

Answer 3

can u find radius when diameter is given ?

Answer 4

no ?

Answer 5

No? Can you just show me the steps?

Answer 6

I know you do:

Interior angle = 360°/12 = 30°
Arc length = a/360°(πd)

Answer 7

but then i'm stuck

Answer 8

yes,
radius = diameter /2 = 12/2 = 6

Answer 9

first we can find area of circle, then divide it by 12

Answer 10

area of circle = pi * r^2

Answer 11

area of slice = pi * r^2/12
r= 6

Answer 12

i'm confused, okay. i'm sorry, i need to find the interior angle and arc length of the slices
AND the area of each slice. if my pizza is 12" in diameter and has 12 slices.

Answer 13

Area =
π(r)2
so pizza area = 3.14*6*6 = 113.04 inch sq

for 12 the part = 113.04/12 = 9.42 sq in

Answer 14

piz·za [ptsə]
(plural piz·zas)
noun
baked dough topped with cheese: a flat round piece of bread dough baked with a variety of toppings, often including tomato sauce and cheese


[Late 19th century. < Italian, "pie"]

Answer 15

Okay so 9.42 sq inch per slice but now i need to find the interior angle and arc length of each slice..

Answer 16

arc length of circle = ?
then just divide it by 12
your interior angle = 30 is correct

Answer 17

so arc length of slice = r*360/12
r= radius

Answer 18

the angle will be 360/12 = 30 degree
the arc length also easy as \[2 \pi r\] = 2*3.14*6 = 37.68 inch so for this 12th part will be 37.68/12 = 3.14 inch only

Answer 19

okay i was doing this:

interior angle = 360°/12 = 30°
arc length = 30°/360° (π • 12)
arc length = 0.0833333333333333 (π • 12)

can you tell me what i was doing wrong or what i need to do ahhh

Answer 20

see above then u can understand or do some drawing in rough book

Answer 21

i did look above and it just makes me confused, can you please tell me straight out what i have to do left? i'm sorry :(

Answer 22

u did nothing wrong, arc length = 0.0833333333333333 (π • 12)=3.1414 inch
which is correct

Answer 23

got this? from arc length , u want area ?

Answer 24

yeah what's the next step?

Answer 25

ohh i see i see

Answer 26

to get area from arc length , u multiply it by (r/2) here r=6

Answer 27

So this is interior angle and arc length of each slice:

interior angle = 360°/12 = 30°
arc length = 30°/360° (π • 12)
arc length = 0.0833333333333333 (π • 12) = 3.1414 inch

Answer 28

yes..

Answer 29

thank you so much oh gosh you've been a great help really, both of you

Answer 30

welcome ^_^
