Given: m∠AKB = 25°
dexar [7]

Answer:

V = 255.98189 pi

SA = 172.64114π

Step-by-step explanation:

The first thing to do is find the radius.

the measure of angle AKO = 1/2 the measure of angle AKB

m< AKO = 12.5 degrees

Now use trig to find AO (aka the radius)

tan(12.5) = AO/25

AO = 25* tan(12.5)

<em>I'm leaving it like this to get a more accurate number</em>

Now to find the volume

the volume of a cone is pir^2h/3

plugging everything in we get:

pi(25*tan(12.5))^2 * 25/3

which is about <u>255.98189 pi</u>

Now for surface area

(this is the moment I realize symbols exist)

SA = πr(r+√h²+r²)

plugging everything in we have

π(25tan(12.5))((25tan(12.5)+√625+(25tan(12.5))^2)

<em>I know it looks like a lot but that's mainly because I left the radius as 25tan(12.5)</em>

The Surface Area is about <u>172.64114π</u>

Help help help help help
Alenkinab [10]

Answer:

8

Step-by-step explanation:

To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.

Match the coordinates with the points on the coordinate plane
Gnesinka [82]

Answer:

Step-by-step explanation:

(-2\frac{1}{2},3\frac{1}{2})

Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.

Answer is point P.

(-3, 6)

Point L represents the given coordinates.

(-4\frac{1}{2},2)

Point P represents the given coordinates.

(2\frac{1}{2},2\frac{1}{2})

Since, x and y coordinates are positive, point will lie in the 1st quadrant.

Point Q represents the given coordinates.

(-1\frac{1}{2},-3\frac{1}{2})

Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.

Point R represents the given coordinates.

Use order of operations on [2+(9x3)]x3
lozanna [386]
[2+(9x3)]x3
Solve for parentheses
[2+(27)]x3
Brackets are solved before the rest of the equation, but always parentheses first
[29]x3=81
The answer is 81.

Hope this helps, and hope I was the brainliest! :)
