Answer 4

first you need to measure the areas of the 2 circles in the figure

Answer 5

do you remember the formula for the area of a circle?

Answer 6

area of a circle is is a=pi(r^2)

Answer 7

yes

Answer 8

so what are the areas?

Answer 9

324 and 28
?

Answer 10

i dont have the best calculator so some things come out weird

Answer 11

the answer is 28/352. Do you see why?

Answer 12

(reduce it before you use it)

Answer 13

that's the probability? 7/88

Answer 14

because its the probability it'll hit the bullseye, which is the area of the inner circle

Answer 15

noooo

Answer 16

I mean me

Answer 17

then i dont understand what your saying >.<

Answer 18

the real answer is 28/324

Answer 19

I wasnt thinking lol

Answer 20

OH okay i was about to ask where 352 came from

Answer 21

so that reduces to 7/81

the reason why is because there are 328 possible square inches that the dart can hit. out of those spaces, 28 are within the bulls eye

Answer 23

you get it?

Answer 24

alrighty, that makes since yeah!

Answer 25

on to the next question :3

Answer 28

if I can

Answer 29
