Answer 3

Answer 4

ok so what formula did you use?

Answer 5

For this one I use the formula, Pi r(l+r)

Answer 6

hahah you still there?

Answer 7

yea sorry i just keep thinking

Answer 8

no its fine.

Answer 9

ok so the radius is half of the diameter so it is 10 for the radius

Answer 10

\[(3.14)10(18.5+10)\]

Answer 11

this is what you got right?

Answer 12

yeah.

Answer 13

\[(3.14)10\] i mean

Answer 14

\[=?\]

Answer 15

first how did you solve it?

Answer 16

This is my equation
Pi(10)(18.5+10)

Answer 17

what I did was I added 18.5+ and 10 which got me, 28.5

Answer 18

So my new equation was pi(10)(28.5)

Answer 19

then I multiplied 10by 28.5 which got me to 285

Answer 20

285pi.

Answer 21

then I pied it. which got me to 895.4

Answer 22

but then I found the area of the circle since it is asking you not to include that with the formula..pir^2

Answer 23

which turns to be this,

pi10^2

which simplifies to

100pi

Answer 24

then pi it and get 314.2

then I subtract it from the total volume

895.4-314.2
which equals 581.2

Answer 25

kay that was a lot.

Answer 26
