son4ous [18]

Answer:

$\$50+\$31.5x$

Step-by-step explanation:

Let

x------> the number of days

y----> the cost of renting a car

we know that

For $x$

$y=\$50+\$35x$

For $x\geq 7\ days$

The rate is equal to

$0.90*\$35=\$31.5$

$y=\$50+\$31.5x$

In this problem. the car has been rented for more than a week

therefore

$x> 7\ days$

The cost of renting a car is equal to

$y=\$50+\$31.5x$

The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
$A=\pi r^2 = \pi\frac{d^2}{4}$

hence the volume is
$V= \pi r^2 L = \pi \frac{d^2}{4} L$

the Length "L" is 36 in
the diameter "d" is 3 in

Find the volume of the cylinder in terms of π.

ValentinkaMS [17]

Hello There!

The volume for a cylinder is Pi*r^2*h

We are going to leave our Answer in terms of pi so first we need to square our radius which we know is 5

Our radius is 25 because we squared 5. Next, we need to multiply 25 by our height which is 11.

25 multiplied by 11 is 275 so our Answer would be 275 $\pi$
