H = 5 ft
Which is the formula
for the volume
of a cylinder?
A. V = a^2 + b^2 + c^2
B. V = (area of the base)(radius)
C. V = (area of the base)(height)
Answers
Answer: C. V = (area of the base)(height)
This applies to any prism. A cylinder is effectively a prism but the base is a circle rather than a polygon.
The cylindrical volume formula you may be more familiar with is
V = pi*r^2*h
note how the pi*r^2 portion is the area of the circular base. So we can replace the pi*r^2 with "area of the base" to end up with choice C.

calculate, in dollars, how much more Jane pays.
Answers
Answer:
$19.15
Step-by-step explanation:
$1=0.626
$1/0.626=£1
$11.99=$11.99/0.626
=$19.15
Answer:
Step-by-step explanation:
£ 0.626 =$ 1
£1 = $ [tex]\frac{1}{0.625}[/tex]
£ 11.99 = [tex]11.99*\frac{1}{0.625}= \frac{11.99*1000}{0.625*1000}\\\\[/tex]

y - 3 = 2(x - 2)
Step-by-step explanation:
Step 1. Solve for slope
m = slope
m = (y2 - y1)/(x2 - x1)
Points: (-2, 3) & (1, 9)
m = (9 - 3)/(1 - - 2)
m = 6/3
m = 2
Step 2. Use the two points and the slope to write the line in point-slope form.
Point-Slope Form: y - y1 = m(x - x1)
Slope-Intercept Form: y = 2x + 7
With the points: (-2, 3) & (1, 9)
Where x1 = -2 y1 = 3, x2 = 1 y2 = 9
Point-Slope Form = y - 3 = 2(x - 2)

Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
Answer:
Step-by-step explanation:
[tex]tan \ A = \frac{5}{12}=\frac{opposite \ site}{adjacent \ side}[/tex]
hypotenuse² = (opposite side)² + (adjacent side)²
= 5² + 12²
= 25 + 144
= 169
hypotenuse = √169 = √13*13 = 13
[tex]Cot \ A = \frac{adjacent \ side}{opposite \ side}=\frac{12}{5}\\\\Cos \ A = \frac{adjacent \ side}{hypotenuse}=\frac{12}{13}\\\\Sin \ A = \frac{opposite \ side}{hypotenuse}=\frac{5}{13}[/tex]

Answer:
Y=4 X= -6 or (-6,4)
Step-by-step explanation:
Okay so
3x+10y=22
-3x-8y=-14
basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 010y minus 8y gives us 2y.22 minus 14 gives us 83x+10y=22
-3x-8y=-14
0+2y=8
Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.
[tex] \frac{2y}{2} = \frac{8}{2} [/tex]
From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.
y= 4
Now we can fill in. You can pick any equation for this but I'm going to chose the first one.
3x+10y=22
we can fill in 4 for y
3x+10(4)=22
3x+40=22
Next we are going to subtract 40 on both sides.
3x+40=22
-40 -40
3x= -18
Next, we're going to divide -18 by 3.
[tex] \frac{3x}{3} = \frac{ - 18}{3} [/tex]
The 3s cancel out leaving us x. -18 divided by 3 is -6.
x= -6

"If the radius of the closed cone is doubled, show algebraically how this affects the surface area in comparison to the original cone."
How do I do this question?
Answers
Answer:
It would help to have the cone area formula:
Area = PI * radius * slant height
Let's say the height is 12cm radius is 5 cm
which makes the (slant height)^2 = 12^2 + 5^2 = 169
slant height = 13
and surface area = PI * 5 * 12 = 188.4955592154
If radius = 10 then (slant height)^2 = 12^2 + 10^2 = 244
slant height = 15.6204993518
surface area = PI * 10 * 15.62 = 376.99
376.99 / 188.4955 = 2
So, if radius is doubled, surface area is doubled.
