Volume = Area * height 
 = (pi/4)*D^2 * h
 = (pi/4)*(40)^2 * 30 
  = 37,680 mm3
so, the answer is (a)

Answer: a. 37,680\ mm^3

Step-by-step explanation:

We know that the volume of a cylinder is given by :-

V=\pi r^2 h, where r is radius and h is height of the cylinder.

Given: The diameter of cylinder = 40 mm

The radius of cylinder =r=\dfrac{40}{2}=20\ mm

The height of cylinder = 30 mm

Then , the volume of the cylinder will be :-

V=(3.14) (20)^2 (30)=37680\ mm^3

Hence, the volume of the cylinder = V=37680\ mm^3

Identify the value of p. Give your answers in simplest radical form. HELP PLEASE!!
VikaD [51]

Answer:

C

Step-by-step explanation:

using the cosine ratio to find p

cos 45° = \frac{adjacent}{hypotenuse} = \frac{6}{p}

cross- multiplying gives

p × cos45° = 6 → [ cos 45° = \frac{1}{\sqrt{2} }]

p × \frac{1}{\sqrt{2} } = 6

multiply both sides by \sqrt{2}

⇒ p = 6\sqrt{2} ( third option on list )

Graph the line with slope 2 passing through the point (1, -3).
Pepsi [2]

Answer:

2x-5=y

I'm not sure how your graphing tool works so I'll give you five or so coordinates

(-1,-7)

(1,-3)

(0,-5)

(2,-1)

(-2,-9)

Step-by-step explanation:

You first need to write an equation that you can graph

Knowing that the slope is two we can write the following equation

2x+b=y

We also know that when x=1 y=-3

This gives us 2*1+b=-3

which means that 2+b=-3

subtract 2 from both sides to figure out the b=-3

This means that the line you have to graph is 2x-5=y

What's 4+ -1 1/3 as a fraction in simplest form
Ivenika [448]
4 + -1 1/3 

Turn 4 into an improper fraction.

4/4 is equal to 12/3. We want both 4 and 1 1/3 to have the same denominator so that they could be subtracted from each other.

New question :

12/3 + - 1 1/3

Turn {-1 1/3} into an improper fraction.

(3 × 1) + 1  = 4/3

So, -1 1/3 = -4/3

Our new question :

12/3 + - 4/3

Simplify.

12/3 - 4/3 = 8/3

Turn into a mixed number.

2 2/3

~Hope I helped!~
