A cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.

Anton [14]

Answer:

Height of cylinder is $\frac{4}{5}\ ft$ .

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

$R = \dfrac{D}{2}$

So, radius, R = $\frac{6}{2} \Rightarrow 3$ feet

Let height of cylinder be $h$ feet.

Formula for volume of cylinder is given by:

$V = \pi R^{2} H$

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

$V = \dfrac{36 \pi}{5} ft^{3}$

Using formula for volume, $V = \pi R^{2} H$

$\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft$

Hence, Height of cylinder is $\frac{4}{5}\ ft$ .

A ladder is leaning against a

vlada-n [284]

Answer:

The angle of elevation is 36.87 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC of the figure

$cos(\theta)=\frac{AC}{BC}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(\theta)=\frac{12}{15}$

$\theta=cos^{-1}(\frac{12}{15})=36.87^o$

Leonard is studying the relationship between the fuel efficiency in miles per gallon (mpg), y, and the speed in miles per hour (

Nataliya [291]

Answer:

D. There is a nonlinear relationship between the speed and fuel efficiency.

Step-by-step explanation:

A desirable residual plot should show a horizontal band with points randomly distributed about the horizontal axis.

Leonard's plot is definitely nonlinear.

The residuals show a good fit to a parabola.

This suggests that the relation between speed and fuel efficiency may be parabolic.
