Answer with Step-by-step explanation:

V=kr²h

Where r is the radius and h is the height of the cylinder

Cylinder A has a volume of 251.2 cubic inches and has a radius of 4 inches and a height of 5 inches.

⇒ 251.2=k×4²×5

⇒ 251.2=80k

⇒k=251.2/80

⇒ k=3.14

We have to find  volume of cylinder B, which has a radius of 3 inches and a height of 9 inches

r=3 inches

h=9 inches

V=3.14×3²×9

 =254.34 cubic inches

Hence, Volume of cylinder B is:

254.34 cubic inches

Find the slope of the line through the given points (8,-3), (5,-3)
fredd [130]
To calculate the slope, you can use the formula
\frac{{y}^{2} - {y}^{1}}{{x}^{2}  -  {x}^{1} }
In this case,
\frac{( - 3) - ( - 3)}{8 - 5}
Your slope is 0/3, which does not make sense so there should be something incorrect about your points.

Dave wants to rent a car for the week. The cost of the car rental is a flat amount of $50 plus $0.12 per mile traveled.
Rasek [7]

Answer:

<h2>B</h2>

Step-by-step explanation:

They give it in plain words.

C(d) = 50 + 0.12d

And as the d is used once and not as a exponent, we can consider this as a variable.
