Find the volume of the cone. Use 3.14 for pi. Round your answer to the nearest TENTH. Only write a number for your answer. with work
Please help.
i dont understand how to do this kind of thing.
Find the volume and surface area (show work please)
Answer:
V= 120 Surface Area= 124
Step-by-step explanation:
Volume
(6 x 8 x 5)/2 = 120
Surface Area
6 x 6 = 36
2[(6 x 8)/2] = 48
2[(8 x 5)] = 80
=124

Which of the following is FALSE for the Rectangle shown? (Highlight ONE)
Answer:
Step-by-step explanation:
Work out the volume of this prism. Write your answer
a in cm?
120cm
30cm
20 cm
Answer:
24,000 cm³
Step-by-step explanation:
Answer:
V = 48000 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = area of end face × length
The end face is a trapezium with area (A) calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 20 , b₁ = 10 and b₂ = 30 , then
A = [tex]\frac{1}{2}[/tex] × 20 × (10 + 30) = 10 × 40 = 400 cm²
Thus
V = 400 × 120 = 48000 cm³

A cylinder had a volume of 100 pi. Find one possible radius and height for the cylinder. Explain how you know your combination is correct.
Answer:
Calculate the volume of a cylinder using the formula V = r2 × π × h. Begin by first finding the area of the circle at one end. Square the radius of the circle and multiply the result by "pi" (the symbol π), or approximately 3.14. Multiply this result by the cylinder's height to get its volume.
Step-by-step explanation:
the height is 4 and the radius is 2

which is the best estimate of 11 1/5 divided by 2 3/4?
. 4
.6
.22
.33
Answer:
4.07
Step-by-step explanation:
11 1/5 divided by 2 3/4
= 11 1/5 ÷ 2 3/4
= 56/5 ÷ 11/4
= 56/5 × 4/11
= (56*4) / (5*11)
= 224/55
= 4.07
The best estimate of 11 1/5 divided by 2 3/4 is 4.07
Estimate the percent: 10 out of 21
The answer would be 47.6% because there is a lot of numbers so the round to the nearest tenth

Is a triangle with sides 4, 6, and 8 a right triangle? Explain your thinking.
Answer:
No it's not
Step-by-step explanation:
In a right triangle the longest side is always the Hypotnuse. With legs a and b and Hypotnuse c, all right triangle follow the Pythagoream Theorem (a^2+b^2=c^2)
If this is a right triangle then it should also follow this rule.
8^2=4^2+6^2
64=16+36
64≠52
So this isn't a right triangle
We can find the solution to the answer by using the Pythagorean Theorem.
a² + b² = c²
4² + 6² = 8²
16 + 36 = 52
8² = 64
52 ≠ 64.
Since 4² + 6² does not equal 8², a triangle with the sides 4, 6, and 8, are not a right triangle.

1. Is ABCD a translation, rotation, or reflection of ABCD? Explain how you can tell.
Answer:
1. Reflection
2. rotation and reflection
3. b', b''
4. 26.3
Step-by-step explanation:
1. It is like looking in a mirror. Its is being reflected across the y axis
2. It is rotated 90 degrees to the right. Then reflected over the x axis.
3. they are the same
4. It is the same as A" B" C" D" so the lengths are the same and you just add them.
Step-by-step explanation:
How do I solve for x? (Please Show Work)
Answer:
x = 17.6
Step-by-step explanation:
use sine
⇒ sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 62 = [tex]\frac{20}{x}[/tex]
sine of 62 is 0.88
⇒ 0.88 = [tex]\frac{20}{x}[/tex]
multiply 20 on both sides
⇒ 0.88 x 20 = [tex]\frac{20}{x}[/tex] x 20
⇒ 17.6 = x
