A cylinder has a height h, and a radius (3h-2)The area of the base is pi (3h-2)^2


The volume of the clinder is V= pi(3h-2)^2h


10. Multiply the polynomials to simplify the expression for the volume:

V=pi(3h-2)^2h by

Answers

Answer 1
Answer:

Answer:

V= 4\pi (9h^2 -12h + 4)

Step-by-step explanation:

Given

Shape: Cylinder

Radius = 3h - 2

Height = h

Base\ Area = \pi (3h - 2)^2

Required

Simplify the volume

The volume is calculated as:

Volume = Base\ Area * Height

Substitute values for Base Area and Height

V= \pi(3h-2)^2*h

Expand the bracket

V= \pi(3h-2)(3h-2)*h

Open brackets

V= \pi (9h^2 -6h - 6h + 4) *h

V= \pi (9h^2 -12h + 4) *h

V= 4\pi (9h^2 -12h + 4)

Ages of patients (in years) in a clinic: 19, 8, 21, 19 (round to the nearest whole ).

Answers

I'm guessing you're looking for the mean or average? That would be the sum of all the ages divided by the numbers of people
So:
19+8+21+19=67
Divided by 4
67/4= 16.75
Rounded up you get 17

carla, bev, and ashley took their unit 2 math test. carla made an 80 and bev made a 75. what was ashleys score on the test if their average was 78.

Answers

Answer:

Ashley = 79

Step-by-step explanation:

Average=(Carla+Bev+Ashley)/(3)=78\n\n(80+75+Ashley)/(3)= 78 \n\n(155+Ashley)/(3)=78\n\n(155+Ashley)/(3)*(3)/(1) =78*3\n\n155+Ashley=234\n

Subtract 155 from both sides;

Ashley = 79

Two parallel lines are crossed by a transversal.What is the value of x?

Could someone tell me how to solve this?

Answers

because both lines are parallel, if you add the 5x+5 to the 115 those would equal 180 degrees

so you have 5x+5 + 115 = 180

combine like terms:

5x + 120 = 180

subtract 120 from both sides

5x = 60

x = 60/5
x = 12
Okay so (5x+5)+115 is going to equal 180. 

1.) (5x+5)+115=180

The next steps is to isolate the x.

2.) 5x+120=180
3.)  -120=-120
4.) 5x=60
5.) /5=/5
6.) x=12 degrees

Then, you check your work by plugging in the numbers.
7.) 5(12)+5+115=180
8.) 60+5+115=180
9.)180=180
