To start, the first thing you need to know is that when you add decimals, you must line the decimal up, meaning, if you were adding 2.7+4.1, you have to make sure 2 is lined up with 4, and 7 is lined up with 1 so that the decimals align. Then, you add straight down from right to left and you get 6.8 as your answer.

Consider the ball that fits perfectly inside the cylinder. The volume of the ball is 3,052.08 cm3. What is the volume of the cyl
mixas84 [53]
We know that

[volume of a sphere]=(4/3)*pi*r³-------> r=∛[(3*Volume)/(4*pi)]
 r=∛[(3*Volume)/(4*pi)]------>  r=∛[(3*3052.08)/(4*pi)]----> r=∛729
r=9 cm

[volume of a cylinder]=pi*r²*h
r=9 cm
h=2*r----> 2*9 -----> 18cm
[volume of a cylinder]=pi*r²*h----->pi*9²*18---> 4578.12 cm³

the answer is
4578 cm³
