What is the volume of a cone with a radius of 4 centimeters and a height of 5 centimeters? please help

Answers

Answer:

V = [tex]\frac{80\pi }{3}[/tex]

Step-by-step explanation:

Using the equation for finding the volume of a cone

V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]

Were "V" is Volume, [tex]\pi[/tex] is pi, r² is radius to the second power, and [tex]\frac{h}{3}[/tex] is height divided by 3.

We can fill in the missing components to find "V" as in for Volume.

V = [tex]\pi[/tex]4²[tex]\frac{5}{3}[/tex]

Now let's simplify

V = 16[tex]\pi \frac{5}{3}[/tex]

Now simplify for the last time

V = [tex]\frac{80\pi }{3}[/tex]

Answer: V = 1649.34

Step-by-step explanation:

The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.

We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21

5^2 = 5 x 5= 25

so pi x 25 x 21 = 1649.34

Answer:

V ≈ 1649.34 ft³

Step-by-step explanation:

Volume of a Cylinder: V = πr²h

Diameter = 2 · radius

Step 1: Define

d = 10 ft

h = 21 ft

Step 2: Substitute and Evaluate

10 = 2r

r = 5

V = π(5)²(21)

V = π(25)(21)

V = 525π

V ≈ 1649.34 ft³

5x +2y = 12
5x −2y = 28

Answers

i used elimination. so you start by adding the 2 equations. |5x+2y=12+5x-2y=28| you end up getting |10x=40| the 2y’s cancel out because on is positive and one is negative. then you divide each side by 10. |x=4| you plug this in for x in the first equation. |5x+2y=12|=|5(4)+2y=12| multiply parentheses. |20+2y=12| subtract 20 from each side. |2y=12-20| add like terms. |2y=-8| divide by 2 on each side. |y=-4|. sorry for the long explanation. in conclusion, x=4 and y=-4, or (4,-4)

what is the solution for 3х + y = -5

Answers

[tex]\tt Step-by-step~explanation:[/tex]

[tex]\tt Solve~for~y:[/tex]

To solve for y, we have to move all of the terms that do not equal to y on one side, and let y be on the other side alone. Do this by subtracting 3x on both sides to cancel it out from the left side and bring it to the right.

[tex]\tt 3x-3x+y=-5-3x\\y=-5-3x\\y=-3x-5[/tex]

[tex]\tt Solve~for~x:[/tex]

To solve for x, we will do the same thing we did to solve for y: move all the terms that do not equal to x to one side, and leave x on another side of the equation. We can do this by first subtracting y from both sides.

[tex]\tt3x+y-y=-5-y\\3x=-y-5[/tex]

Then, we divide all terms by 3 to isolate the x.

[tex]\tt \frac{3x}{3}=x\\\\ \frac{-y}{3}=\frac{-y}{3} \\\\\frac{-5}{3}=\frac{-5}{3}[/tex]

[tex]\tt x=-\frac{y}{3} -\frac{5}{3}[/tex]

[tex]\lare\boxed{\tt Our~final~answer:~y=-3x=5,~x=-\frac{y}{3}-\frac{5}{3} }[/tex]

Step-by-step explanation:

Let x represent the smaller number and y represent the larger number.

ATQ,

The sum of twice a number and a larger number is 145.

2x+y=145 ...(1)

The difference between the numbers is 55.

x-y=55 ...(2)

Hence, the two equations that represent the situation are 2x+y=145 and x-y=55.

24% is 120% of what number?

Answers

Answer:

Step-by-ste24 is 120% of [20]

I don't know if you meant 24 is 120% of x but if that is what you meant, then the answer would be 20. If you meant 24% is 120% of x then x=.2.

24 is 120% of 20 because 20*1.2=24

24% (AKA .24) is 120% of .2 because .2*1.2=.24 and .24=24%
