What is the volume of a sphere with a diameter of 4 meters? (Use 3.14 for π.)

mixer [17]

Answer:

volume of the sphere = $33.493m^3$

Step-by-step explanation:

Given:

$Diameter= 4 m$ , $Radius = 4/2 =2 m$

Volume of a sphere= $\frac{4}{3} *\pi* r^3$

= $\frac{4}{3} *\pi* 2*2*2$ : $\pi =3.14$

= $\frac{4}{3} *3.14*2*2*2$

= $1.33*3.14*2*2*2$

= $33.493m^3$

The volume of the sphere with the radius of 2 m is $33.493m^3$

A taxi cab charges a flat rate of $3in addition to $1.80 per mile,m, traveled. Jennifer has no more money than $25 to spend on a

PIT_PIT [208]

Answer:

1.80m + 3 ≤ 25

Step-by-step explanation:

We have a flat rate of $3, which means that's the base value. Now, we see that Jennifer has to pay $1.80 per mile, which means that when she has ridden m miles, she has to pay 1.80m. However, remember to add 3 to this:

1.80m + 3

Jennifer only has $25 to spend, so she can't spend any more than 25. This means that the money she can spend must be less than or equal to $25:

1.80m + 3 ≤ 25

Hope this helps!

Find an equation of the line described below. Write the equation is slope-intercept from ( solved for y), when possible. Through

Sladkaya [172]

Answer:

The equation of the line that is passing through the point (5,4) and is parallel to x-axis would be $y=4$

Step-by-step explanation:

Given that the line passes through the point (5,4).

As the line is parallel to the x-axis, the slope of the line would be zero.

And we have point (5,4) from which the line is passing.

So, $x_1=5\ ,\ y_1=4\ and\ m=0$

The equation of the line passing through point $(x_1,y_1)$ is

$y-y_1=m(x-x_1)\\y-4=0(x-5)\\y-4=0\\y=4$

So, the equation of the line that is passing through the point (5,4) and is parallel to x-axis would be $y=4$
