The complete question is
<span>Four golf balls are packaged in a cylindrical container as shown below. The balls just touch the top, bottom, and sides of the cylinder. The diameter of each ball is 4cm.
1) </span><span>What is the volume of the cylinder rounded to the nearest cubic centimeter?
</span>2) <span>What is the total volume of the four balls rounded to the nearest cubic centimeter?
</span>3) <span>What percent of the volume of the container is occupied by the four balls?
</span><span>
Part 1) volume of the cylinder=pi*r</span>²*h
<span>r=4/2----> 2 cm
h=4*4----> 16 cm
</span>volume of the cylinder=pi*2²*16----> 200.96 cm³----> 201 cm³
the answer Part 1) is 201 cm³
Part 2) volume of a sphere=(4/3)*pi*r³ ( is equal to volume of one <span>golf ball)
</span>r=2 cm
volume of a sphere=(4/3)*pi*2³ ----> 33.49 cm³
so
volume of four golf ball-----> 4*33.49----> 133.97 cm³----> 134 cm³
the answer part 2) is 134 cm³
part 3)
volume of cylinder=201 cm³
volume of the four golf ball=134 cm³
so
if 201 cm³-----------> 100%
134 cm³--------> x
x=134*100/201----> x=66.67%
the answer part 3) is 66.67%
Answer:
2x-8+3x+2=4x+10+3x-6
We move all terms to the left:
2x-8+3x+2-(4x+10+3x-6)=0
We add all the numbers together, and all the variables
2x+3x-(7x+4)-8+2=0
We add all the numbers together, and all the variables
5x-(7x+4)-6=0
We get rid of parentheses
5x-7x-4-6=0
We add all the numbers together, and all the variables
-2x-10=0
We move all terms containing x to the left, all other terms to the right
-2x=10
x=10/-2
x=-5
Step-by-step explanation:
I do believe that Ben's statement is always true because of the fact that when you divide a positive by a negative, or a negative by a positive, it will always equal a negative. For the equation 5.4/-6.8 the answer is -0.79411764705. And the equation -6.8/5.4 is equal to -1.25925925926. It will always equal to less then zero, except when you divide by zero.
