Question

Betty and Alexander are standing in a big circle with 88 other people all facing the middle of the circle. Betty and Alexander are directly across from each other. The average width in the crowd is two feet. How far, approximitly are Betty and Alexander from each other?

Answer 1

@hartnn

Answer 2

The average width is 2 feet, so lets say all of them are approx 2 feet apart.
Now , 88 people standing will have 88 gaps each of 2 feet.
So, the circumference of circle will be 88*2 = 176 feet.
ok with this ?

Answer 3

there are 90 people in the circle though.

88+betty and alexander

Answer 4

so it would be 180 feet.

Answer 5

ohh!! sorry circumference = 90*2 = 180 feet
yes.
now can u find the diameter of circle ?

Answer 6

dont remember. :[

Answer 7

ok, Circumference = \(\pi\) *diameter.
now whats the diameter ?

Answer 8

90?

Answer 9

since they both are directly across each other , the are on the end points of diameter
so the distance between them is = diameter = 28.648 feet approx
does this make sense ?

Answer 10

not really. lol. i barly understand what 90/ \(\pi\) = 90/3.14 = 28.648 feet means, i cant see equations only drawing idk why though.

Answer 11

\(\pi\) is an irrational number = 3.14 or 22/7 approx.
and it is the ratio of circumference to diameter.

Answer 12

ik what pi is. its all those slashes and parethesis and everything like that

Answer 13

/ means division.

Answer 14

\(\pi\)=i cannot see the equation so, just type it, dont use the equation button

Answer 15

i can't see the \(\\) and what it means.

Answer 16

ok, circumference = pi * diameter
as circumference = 180
diameter = 180/ pi = 57.296 feet = distance between them

Answer 17

wait, yo said the diameter is 28.648 feet approx

Answer 18

that was typing error, when i saw all comments again , i found that circumference = 180 and not 90
so diameter = 57.296 feet.

Answer 19

okay. thank you.

Answer 20

i gave you a medal

Answer 21

welcome :)
