A cylinder has a volume of 36 cubic inches. What is the volume of a cone if it has the same radius and height as the cylinder?

Answers

Answer:

12 cubic inches

Step-by-step explanation:

volume of a cylinder= pi*r2*height

but we are given 36 as cylinder volume.

Therefore , 36 = pi*r2* height

r2*height = 36/pi, let call this equation 1

volume of a cone = pi*r2*height/3;

but from equation 1, r2*height =36/pi, substituting this value in volume of cone.

volume of cone= pi*(36/pi)/3 = 12 cubic inches

4 8.95h + 10 < 115

Step-by-step explanation:

Answer: 4) 8.95h + 10 < 115

Step-by-step explanation:

We know the inequality will be equal to less than 115 since it states that the order was less than $115.

The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115

8.95h + 10 < 115

(h in the given equation is the amount of shin guards)

Find the area and the circumference of a circle with radius 2yd. Use the value 3.14 for pie and do not round your answer. Be sure to include the correct units in your answer

Answers

Answer:

circumference:  12.56 yd

area:  3.14(2 yd)² = 12.56 yd²

Step-by-step explanation:

The circumference formula is C = 2πr (pi, not pie), where r is the radius.

When r = 2 yd and π ≈ 3.14, the circumference is:

C = 2(3.14)(2 yd) = 12.56 yd

[tex]in triangle ABC, AB=7, BC=10, and the measure of angle B=80, to the nearest 10th, what is b[/tex]

Answers

Answer:

b = 11.0

Step-by-step explanation:

From the given properties of the triangle,

b = AC

Applying the cosine rule, we have;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2acCos B

   = [tex]10^{2}[/tex] + [tex]7^{2}[/tex] - 2(10 x 7) Cos 80

   = 100 + 49 - 140 x 0.17365

   = 149 - 24.311

   = 124.689

b = [tex]\sqrt{124.689}[/tex]

  = 11.1664

b = 11.0

Rope packaged in 80-foot lengths
must be cut into 12-foot pieces to
do a certain job. If 28 such pieces
of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28

Answers

Answer:

it would be 5

Step-by-step explanation:

any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left

80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)

then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed

the whole thing >

80* 5 = 400

400/28 = 33.33

33.33- 28 = 5.33

What is the distance between (2. 6) and (7, 6)​

Answers

Answer:

5

Step-by-step explanation:

Hey There!

So first off the y values are the same so to find the distance between the two points all we have to do is subtract the largest x value from the smallest x value

7-2=5

Therefore the distance between the two points is 5

Answer: 5

Step-by-step explanation:

D = √(x₂ - x₁)² + (y₂ - y₁)²

x₁ =2 y₁ =6 x₂ =7 y₂ =6

D =√(7-2)² +(6-6)²

D=√(5)² +(0)²

D =√25

Step-by-step explanation:

Given

[tex]\angle NOP = 150^\circ[/tex]

See attachment for circle O

Required

Find [tex]arc\ MN[/tex]

The sum of angles in a semi-circle is 180 degrees.

So:

Answers

The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:

Fred's age is 82.

Amanda's age is 27.

Catherine's age is 14.

Blake's age is 12.

The equation that represents Fred's age is: 1 + 3x =

Where x is Amanda's age

Fred and Amanda's age : 109 = 1 + 3x + x

4x + 1 = 109

4x = 109 - 1

4x = 108

x = 108 / 4

x = 27

Fred's age = 1 + (3 x 27) = 82

The equation that represents Blake's age is: b =  2c - 16

Where: b = Blake's age

c = Catherine's age = 2 + b

b = 2(2 + b) - 16

b = 4 + 2b - 16

16 - 4 = 2b - b

12 = b

Catherine's age = 12 + 2 = 14
