To solve:

The diameter is already given (2.5), and it can be divided by 2 to find the radius.

2.5/2=1.25

Plug 1.25 and Pi into the equation for a sphere to find the volume:

(4/3)(1.25^3)(3.14)=8.177

Answer: About 8.18 cm^3

Answer: 8.18 cubic centimeters

Step-by-step explanation:

Given : A ball bearing is shaped like a sphere .

The diameter of ball = 2.5 centimeters

Then , the radius of the ball =\dfrac{2.5}{2}=1.25\text{ cm}

We know that the volume of a sphere is given by :-

\text{Volume}=\dfrac{4}{3}\pi r^3

Then , the volume of ball is given by :-

\text{Volume}=\dfrac{4}{3}(3.14) (1.25)^3\\\\\Rightarrow\ \text{Volume}=8.17708333333\approx8.18\text{ cubic centimeters}

What is the slope of the line that passes through the points (-9, 8) and (−21,10)
rosijanka [135]

Answer:

-1/6

Step-by-step explanation:

(10 - 8)/(-21 + 9)= 12/-12= -1

y - 8 = -1(x + 9)

y - 8 = -x - 9

y = -x - 1

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an
kari74 [83]

Given:

The equation of given line is

y=3x-4

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

y=3x-4

On comparing this equation with slope intercept form y=mx+b, we get

m=3

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

m\times m_1=-1

3\times m_1=-1

m_1=-\dfrac{1}{3}

Point slope form of a line is

y-y_1=m(x-x_1)

Where, m is the slope.

The slope of perpendicular line is -\dfrac{1}{3} and it passes through the point (9,5). So the equation of the line is

y-5=-\dfrac{1}{3}(x-9)

y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)

y-5=-\dfrac{1}{3}x+3

Adding 5 on both sides, we get

y-5+5=-\dfrac{1}{3}x+3+5

y=-\dfrac{1}{3}x+8

Therefore, the equation of required line is y=-\dfrac{1}{3}x+8.
