Lets get started :)

The Volume formula of a Cylinder is 
V = \pir²h
(r = radius, h = height)

The radius given is 8 and the height is 4, We can plug in the known values

V = \pi(8)²(4)
   = \pi256
   = 256\pi units³ (You can leave the answer in this form)
   ≈ 804.2 units³ (approximately)

Units³ because it is a volume (3D shape)

A conical-shaped umbrella has a radius of 0.4 m and a height of 0.45 m. Calculate the amount of fabric needed to manufacture thi
bonufazy [111]

Answer:

The correct answer will be "0.756596 m²".

Step-by-step explanation:

The given values are:

The radius of an umbrella,

r = 0.4 m

The height of an umbrella,

h = 0.45 m

As we know,

The lateral surface of an umbrella will be:

⇒  \pi r\sqrt{r^2+h^2}

On substituting the values, we get

⇒  \pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}

⇒  0.756596 \ m^2

So that the amount of fabric needed will be "0.756596 m²".

What is α, the probability of a Type I error if the null hypothesis, H0, is: Carmin believes that her chemistry exam will only c
baherus [9]

Answer:

The probability of falling into a type I error, when testing a hypothesis test, consists of:

Probability of rejecting the null hypothesis when, in reality, this hypothesis is true.

Probability of rejecting the null hypothesis when, in reality, this hypothesis is true, is:

Probability of Affirm that Chemistry exam will NOT cover only chapters four and five, since the Chemistry exam will cover only chapters four and five.

That is, alpha is the probability that Carmin decides to study additional chapters, unnecessarily.

How are perpendicular lines and interesting line alike? How are they different?
sleet_krkn [62]
Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...

They are different because perpendicular lines cross one another in a specific way.  The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing.  It could be at any angle.
