Answer 8

i green can u fan me back?

Answer 9

so V= 324.99 i multiplied it

Answer 10

wow people asks some hard questions sometimes

Answer 11

its what the site is for

Answer 12

@iGreen did i do it right?

Answer 13

Yes, you did.

Answer 14

thank you so how will i find how many pennies will fit?

Answer 15

Now find the volume of a penny.

Answer 16

the equation will be V= (3.14)(?)(0.061)

Answer 17

will it still be 3^2

Answer 18

@iGreen

Answer 19

@perl Would we use the formula for the sphere to find the volume of the penny?

Answer 20

Simplify that and divide it

Answer 21

divide what

Answer 22

Nevermind.

\(V = \pi r^2 h\)

Plug in what we know:

\(V = (3.14)(3^2)(0.061)\)

Answer 23

Simplify that

Answer 24

i got 1.72386

Answer 25

Yes, now divide that to 324.99

Answer 26

so 324.99/1.72386 = 188.524

Answer 27

Yes, so approximately 188 pennies can fit in the cylinder.
