Answer:
24 unit^2.
Step-by-step explanation:
Area = 1/2 * base * height
= 1/2 * 12 * 4
= 1/2 * 48
= 24 unit^2.

Consider a cylinder with height h=3x-4 and radius r=3x+2 Determine a simplified expression for the ratio of the volume of the cylinder to its surface area. Make a sketch of the cylinder
Step-by-step explanation:
Given that,
The height of the cylinder, h = 3x-4
The radius of the cylinder, r = 3x+2
The volume of the cylinder is :
[tex]V=\pi r^2 h[/tex]
The surface area of the cylinder is :
[tex]A=2\pi r(r+h)[/tex]
The ratio of the volume of the cylinder to the surface area of the cylinder is :
[tex]\dfrac{V}{A}=\dfrac{\pi r^2h}{2\pi r(r+h)}\\\\\dfrac{V}{A}=\dfrac{rh}{2(r+h)}[/tex]
Put all the values,
[tex]\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(3x+2+3x-4)}\\\\\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(6x-2)}[/tex]
Hence, this is the required solution.

2/6
5/12
1/6
Answer:
1/6
Step-by-step explanation:
There are six sides, but only one side has 5 dots, meaning 1/6 has 5 dots. Therefore the probability is 1/6.

Answer:
[tex] V_{weights} =1,243 \: cm^3 [/tex]
Step-by-step explanation:
Radius of weight [tex] r_1=\frac{20}{2}= 10 \:cm[/tex]
Radius of hole [tex] r_2=\frac{2}{2}= 1 \:cm[/tex]
Height of weight as well as hole (h) = 2 cm
Volume of weights = (Volume of one weight - volume of hole)
[tex] \therefore V_{weights} = 2 (\pi r_1^2 h - \pi r_2^2 h)[/tex]
[tex]\therefore V_{weights} = 2 \pi (r_1^2 - r_2^2 )h[/tex]
[tex]\therefore V_{weights} = 2 (3.14)(10^2 - 1^2 )2[/tex]
[tex]\therefore V_{weights} =12.56(100 - 1 )[/tex]
[tex]\therefore V_{weights} = 12.56(99)[/tex]
[tex]\therefore V_{weights} =1,243.44[/tex]
[tex]\therefore V_{weights} \approx 1,243 \: cm^3 [/tex]
