A graduated cylinder with a radius of 3 cm contains water to a height of 9 cm. Yann adds 15 steel balls, each with a diameter of 3 cm. What is the total volume of the contents in the cylinder after the balls are added? Use 3.14 to approximate pi and express your answer in hundredths.

Answers

find volume
Vcylinder=hpir^2

volume of cylinder=(4/3)pir^3


water to height of 9
radis i3
V=9*pi*3^3
V=81pi

the balls
15 of them
diameter/2=radius
3/2=1.5
radous=1.5
15V=15(4/3)(pi)(1.5^3)
15V=20pi(3.375)
15V=67.5pi


addd tehm

81pi+67.5pi=148.5pi
aprox pi=3.14
148.5*3.14=466.29 cm^3

I dont know the answer. Can someone help me ?

Answers

Answer:

V = 18 pi unit ^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi r^2 h

where r is the radius and h is the height

V = pi * (3)^2 *2

V = pi *9(2)

V = 18 pi unit ^3

The volume of a cylinder is

(Pi) x (radius squared) x (height) .

Using this, you can FIND the volume of any cylinder, even when you don't know it. This one is 18 pi cubic units.

Answer:

The Slope is -5/2

Y-intercept is -25

The equation is y=(-5/2)x-25

Step-by-step explanation:

Choose a first point and a second point

Remember points are (x,y)

Use (y₂ - y₁)/(x₂ - x₁)

y-intercept: The initial value of a linear relationship, the place that a linear equation crosses the y axis, represented by the letter b, the point (0,b).

Linear Relationship -the equation that represents a straight line often represented by y=mx+b where m is the slope and b is the y-intercept.

State whether the lines in each pair are parallel. explain.
a) y=3x+4 y=—3x+4

Answers

Answer:

They are not parallel. they would have to have the same slope to be parallel.
