have a radius of 3 inches and a height of 12 inches. The
hemispheres have a radius of 3 inches.
How much confetti will they need to fill one of the containers?

40 minutes

step-by-step explanation:

add the time and multiply by 2

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
