A cylindrical pipe is 25 ft long and has a volume of 900ft3 find it's approximate diameter to the nearest hundredth of a foot

Answers

Answer:

Diameter of the pipe ≈ 6.77 ft

Step-by-step explanation:

Volume of a cylinder = πr²h

Here, r = Radius of the cylindrical pipe

h = Length of the pipe

Volume of the pipe = 900 ft³

Length of the pipe = 25 ft

By substituting the given values in the formula,

900 = π(r)²(25)

r² = [tex]\frac{900}{25\pi}[/tex]

r = √11.459

r = 3.385

Diameter = 2(radius)

                = 2(3.385)

                = 6.77 ft

The diameter of the cylinderi is 6.77ft

Volume of a cylinder

the formula for calculating thevolume of a cylinder is given as

V = pi d²/4 × h

Given the following

V = 900ft³

h = 25ft

Substitute the given parameters

900 = 3.14 × d²/4 × 25

900 = 19.625d²

d² = 45.859

d = 6.77ft

Hence the diameter of the cylinderi is 6.77ft

There are 22,521 more people living in the suburbs of a city than in the city. If 17,245 people live in the​ city, how many people live in the​ suburbs?

Answers

Answer:

Number of people in the suburbs= 39,766

Step-by-step explanation:

Giving the following information:

22,521 more people are living in the suburbs of a city than in the city.

Number of people in the city= 17,245

To calculate the number of people that lives in the suburbs, we need to use the following formula:

Number of people in the suburbs= Number of people in the city + 22,521

Number of people in the suburbs= 17,245 + 22,521

Number of people in the suburbs= 39,766

The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.

Answers

Answer:

speed of the rocket is 6feet

Step-by-step explanation:

Complete question

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?

Note that the average rate is also known as the speed

Average rate = h(3)-h(1)/3 - 1

h(3) = 3+70(3) - 16(3)^2

h(3) = 3 + 210 - 144

h(3) = 69

h(1) = 3+70(1) - 16(11)^2

h(1) = 3 + 70 - 16

h(1) = 73 -16

h(1) = 57

Average rate = 69-57/3-1

Average rate = 12/2

Average rate = 6ft/s

This shows  that the speed of the rocket is 6feet

A car that is purchased got 24000 is expected to depreciate at a rate of 7% per year. If the function f(x)=ab^x models this situation, which function could be used to find the value of the car after 10 years?

Answers

Answer:

FV= 24,000*(1.07^-10)

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $24,000

Decrease rate (d)= 7%

Number of periods (n)= 10 years

To calculate the value of the car after 10 years, we need to use the following formula:

FV= PV*(1+d)^-n

FV= 24,000*(1.07^-10)

FV= $12,200.38
