If the radius of the glass container is 2 inches and the height is 3 inches, how much wax will she need to fill the container?
Answer:
ans is 5 container
Step-by-step explanation:
because 3+2=5
and in my first class is seen the answer
She needs to fill 12 cubic inches of wax in the container.
What is volume?The volume of a thing is the area that it takes up in three dimensions. Simply put, objects occupy space.
Given, the radius of the glass container is 2 inches and height is 3 inches.
To fill the maximum wax in the glass container,
we will find the volume of glass container.
Volume of glass container
= Volume of cylinder.
= π r² h
= π(2)² (3)
= π 4 x 3
= 12π cubic inches.
Therefore, 12 cubic inches of wax she needs to fill.

Find the measure of unknown angles
Answer:
1360
Step-by-step explanation:
I know because I get all a's but then again I might be wrong I didn't take my time so sorry
Answer:
x = 110°
Step-by-step explanation:
∠ QRS = ∠ YRT = 110° ( vertically opposite angles )
∠ PQR = 180° - 120° = 60° ( adjacent angles )
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360°, that is
110 + 60 + x + 80 = 360
250° + x = 360° ( subtract 250° from both sides )
x = 110°

Answer:
angle BAD = 180 -2x
angle BCD = x given
angle BCD is an inscribed angle
angle DOB = 2 (angle BCD)
angle BAD = 180 -angle DOB 2 tangent theorem
Step-by-step explanation:
Answer:
[tex] m\angle BAD= (180 - 2x)\degree [/tex]
Step-by-step explanation:
[tex] m\widehat {BD} =2\times m\angle BCD[/tex]
(By inscribed angle theorem)
[tex] m\widehat {BD} =2x\degree [/tex]
[tex] m\widehat {BCD} =360\degree - m\widehat {BD}[/tex]
(By arc sum property of a circle)
[tex] m\widehat {BCD} =360\degree - 2x\degree [/tex]
[tex] m\angle BAD=\frac{1}{2} (m\widehat {BCD}-m\widehat {BD}) [/tex]
(by property of intersecting tangents outside of the circle)
[tex] m\angle BAD=\frac{1}{2} [(360\degree - 2x\degree) -2x\degree] [/tex]
[tex] m\angle BAD=\frac{1}{2} (360\degree - 2x\degree -2x\degree) [/tex]
[tex] m\angle BAD=\frac{1}{2} (360\degree - 4x\degree) [/tex]

What is an equation of the line that passes through the point (6,1) and is perpendicular to the line 2x+3y=18?
Answer
y = 3/2x -8
Step-by-step explanation:
The first thing you should do is change the equation into slope intercept form. Subtract 2x from both sides to get: 3y = -2x + 18. Divide all parts of the equation by 3 to get your equation in slope intercept: y = -2/3x + 6. One thing you should know when finding the slope of a perpendicular line is that it is the opposite reciprocal. So, the slope is going to be 3/2. This is your current equation: y = 3/2x + b. Plug in the point to the equation, it should look like this: 1 = 3/2(6) + b. Multiply 3/2 by 6 to get 9. This is what it should look like: 1 = 9 + b. Then, subtract 9 from both sides of the equation to get your y-intercept of -8. Go back to your other equation and plug in -8 for b. This is your final equation: y = 3/2x -8.

Can you find the midpoint of the segment with the following endpoints.
(-7,-5) and (-4,2)
9514 1404 393
Answer:
(-5.5, -1.5)
Step-by-step explanation:
The midpoint is the average of the end points:
((-7, -5) +(-4, 2))/2 = (-7-4, -5+2)/2 = (-11, -3)/2 = (-5.5, -1.5)
The midpoint of the segment is (-5.5, -1.5).

7k + 4(k + 4)
A.8k + 16
B.11k + 16
C.7k + 1k + 16
D.27k
Answer:
B. 11k + 16
Step-by-step explanation:
We have an expression and are asked to combine like terms.
To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.
(4(k) + 4(4))
4k + 16
7k + 4k + 16.
Since 7k and 4k are like terms since they end in the same variable, we can only add them.
7 + 4
11
11k + 16
