@sleepyjess was it the 4pi(r).2

Answer 5

nope that was the SA not V

Answer 6

\(\dfrac{4}{3}\pi r^3\)

Answer 7

it shows you that r is 5
\(\dfrac{4}{3}\pi 5^3\)

Answer 8

is it 102.5 ? @sleepyjess

Answer 9

you with me so far? @ninaesb

Answer 10

@sleepyjess yes i am . but i got 102.5....

Answer 11

\(5^3=125\\125*3.14=392.5\\392.5*1.33333=?\)

Answer 12

@sleepyjess i got 510.25...

Answer 13

hmmm
wierd
it should come out to 523.333333...
which shows that they have made an error in the answer choices so I would put B

Answer 14

ok I see what you did wrong
you must have done 392.5*1.3
to get the exact answer you have to put 4/3 into your calculator then do ans*392.5

Answer 15

but even if you dont do the 4/3 step you MUST add on those extra 3's or it wont come out even close to correct

Answer 16
