Question

Adanna had a glass cylinder with a radius of 6 cm and a height of 25 cm. She placed 3 balls, each with a diameter of 6 cm, into the cylinder. She filled the rest of the cylinder with colored water.



How many cubic centimeters of colored water did she use?

Answer 2

I got 2486.88cm^3 is that correct

Answer 3

Answer 4

\[\pi*r^2*h_{cylinder~volume} = (6cm)^{2}*(25cm)*\pi = 900\pi_{volume~cylinder}\]

\[\frac{ 4 }{ 3 }(3cm)^{3}*\pi*3 = 339cm^{3}_{~balls}\]

\[(900\pi-339)cm^{3} = 2487cm^{3}_{water}\]

Answer 5

nice work @Samara89

Answer 6

so the answer is 2487

Answer 7
