A cone has a slant height that measures 24 feet and a radius that measures 13.5 feet. What is the surface area of the cone? ​

Answers

Answer 1

Surface area of the cone is 1589.625 feet²

What is cone?

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting apex that is common to all  points on the base that lie in a plane that does not contain the apex.

Given,

Slant height of the cone l = 24 feet

Radius of the cone r = 13.5 feet

Surface area of cone

= πr² + πrl

= 3.14(13.5)² + 3.14×13.5×24

= 3.14(182.25) + 3.14(324)

= 572.265 + 1017.36

= 1589.625 feet²

Hence,  1589.625 feet² is the surface area of the cone.

At track practice, Coach Wilson told the team to split into groups of four for a special relay. The first runner had to run 1 lap around the track (440 yards). The second runner had to run 2 laps around the track. The third runner had to to run 3 laps around the track. The final runner had to run 4 laps around the track (1 mile). How many yards did each relay team team have to run altogether? *

Answers

You can multiply the number of laps each person ran by the yards in each lap and then add them together:

440 + 2(440) + 3(440) + 4(440)
= 440 + 880 + 1,320 + 1,760
= 4,440 yards

Or you can add the laps first, then multiply by the yards in each lap
(1 + 2 + 3 + 4)(440)
= 10 x 440
= 4,400 yards

hey guys, can someone tell me the answer for this question?
[tex] \sqrt[2]{24 + 12} \: \times \sqrt{ {6}^{4} } \times {5}^{2} [/tex]

Answers

Answer:

root 24+12 is root 36 which is equal to 6

4 root of 6 is 36 the power of 2 which is equal to 36

5 the power of 2 is 25

then when we multiple 6x36x25

it's 5400

Answer:

Answer = 1080

Step-by-step explanation:

Hey there!

Here's the initial equation:

[tex]\sqrt{24+12} * \sqrt{6^4 * 5^2}[/tex]

What I'll do now is sum what's in the left root.

[tex]\sqrt{36} * \sqrt{6^4 * 5^2}[/tex]

Since [tex]\sqrt{36}[/tex] = 6, we get this equation:

[tex]6 * \sqrt{6^4 * 5^2}[/tex]

Now: You can see that the five is elevated to the second. Since it is a square root, you can just pop it out:

6 * [tex]5\sqrt{6^4}[/tex]

6 * 5 = 30, so here's what you got:

[tex]30\sqrt{6^4}[/tex]

At this point you should see that:

[tex]6^4[/tex] = 6 * 6 * 6 * 6

6 * 6 * 6 * 6 = 36 * 6 * 6

36 * 6 * 6 = 36 * 36

36 * 36 = 36²

Now you have this:

[tex]30\sqrt[2]{36^2}[/tex]

Since it is a square root and a square number, you can do just as with the five: Pop it out! (When you take numbers out of the root they multiply, they do not add. Never forget that ;).

30 * 36 = 1080

Answer = 1080

Write [tex]cot^{2} x (1+tan^{2} x)[/tex] Then simplify the expression so no quotients appear

Answers

Step-by-step explanation:

From Trig

1 + tan²x = Sec²x

Also

Sec²x = 1/cos²x

Now

Cot²x = 1/tan²x = cos²x/sin²x

Putting all together

Cot²x(1+tan²x)

= Cot²x(sec²x)

= cos²x/sin²x(1/cos²x)

cos²x on the numerator and that one the denominator cancels out

we have

= 1/sin²x

From Trig

1/sin²x = cosec²x

So Our Answer = cosec²x.

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?

Answers

Answer:

ΔT = ( -19°C - 11°C) = -30°C

Step-by-step explanation:

When we have a given variable, let's call it X, the change of X in a given interval is written as:

ΔX = (X₂ - X₁)

Where:

X₂ = final value of the variable

X₁ = initial value of the variable.

In this case, we have the temperature, and we know that the initial temperature is 11°C, then:

T₁ =  11°C

While the final temperature is -19°C, then:

T₂ = -19°C

Then the change will be:

ΔT = ( -19°C - 11°C) = -30°C

This is the wanted expression.
