What the volume of a cylinder with a diameter of 6mm and a height of 7 mm.it says it’s 700 something but the only answers on the test are as low as 100 and highest is 230? Help plz
8th grade math*
Answers
Answer: 197.82mm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where,
π = 3.14
r = Diameter/2 = 6mm/2 = 3mm
h = 7mm
Volume = πr²h
= 3.14 × 3² × 7
= 3.14 × 9 × 7
= 197.82mm³
The volume of the cylinder is 197.82mm³

Pete bought a house in 2009 for $200,000.
The value of his house increased by 10%
annually.
Answers
Answer:
Value of house in 2021 = $627,680 (Approx.)
Step-by-step explanation:
Given:
Value of house in 2009 = $200,000
Rate increased per year = 10% annually
Find;
Value of house in 2021
Computation:
Number of year = 2021-2009 = 12 year
Value of house in 2021 = Value of house in 2009[1+Rate increased per year]ⁿ
Value of house in 2021 = 200,000[1+10%]¹²
Value of house in 2021 = 200,000[1+0.1]¹²
Value of house in 2021 = 200,000[1.1]¹²
Value of house in 2021 = 200,000[3.1384]
Value of house in 2021 = $627,680 (Approx.)
A cylinder has a diameter of 14 cm and a volume of 112 pi.
What is the height in, centimeters, of the cylinder?
(PS I am literally giving 15 points for the correct answer!!!)
HELP! :(
Answers
Diameter = 14 cm
Radius = 7 cm (14/2)
Volume = 112 pi
Volume of cylinder = pi(radius)^2 h
112pi = pi(7)^2 h
Divide both sides
112 = 49 h
h = 112/49
h = 2.285 centimeters

Kallisto built a rectangular sign that measured 2 and 3/4. The width is 1 and 1/4 shorter than the length. To find the area, multiply the length and width. What is the area in square feet write an equation to solve it
Answers
Answer:
l = 1 5/16
w = 1/16
A = 21/16 x 1/16 = 21/256
Step-by-step explanation:
Perimeter = 11/4
l = length
w = l - 5/4
2l + 2(l - 5/4) = 11/4
2l + 2l - -5/2 = 1/4
multiply each side by 4
8l + 8l - 10 = 11
16l = 21
l = 21/16 or 1 5/16
width = 21/16 - 20/16 = 1/16

Answers
Answer:
for the first 14 hours it doubles to 20,000, then once it reaches 28 hours it'll be 40,000. its an exponential growth

Sally found 33 fossils. She found twice as many plant fossils as animal fossils. How many of each type of fossil did she find
Answers
Answer:
a = 11
b = 33
Step-by-step explanation:
Given :
Total fossil found = 33
Let :
Number of plant fossil = b
Number of animal fossil = a
a + b = 33
Plant fossil = 2 times number of animal fossil
b = 2a
Put b = 2a
a + 2a = 33
3a = 33
Divide both sides by 3
3a/ 3 = 33/3
a = 11
a + b = 33
11 + b = 33
b = 33 - 11
b = 22
The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of o°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below O°C (denoted by negative numbers) and some give readings above O C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places. A. -1.48B.-1.89 C. -1.63 D. -1.75
Answers
Solution :
It is given that the Precision Scientific Instrument company Manufactures thermometers that provide readings at 0 degree Celsius for the freezing point of water.
A quality control analyst examines the thermometers which provide readings in the bottom of 4%.
Using the standard normal table, we get
P(z < z) = 4%
P(z < z) = 0.04
See the probability of 0.04 in the standard normal corresponding to the z-value is = -1.75
Therefore,
P(z < -1.75) = 0.04
z = -1.75
So the temperature reading that separates the bottom of 4% from the other thermometers is - 1.75°C
Therefore correct option is (D). -1.75

A satellite is 24,400 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.
Answers
Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.
AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then
(x + 4000)^2 = (13200)^2 + (4000)^2
x = sqrt(13200^2 + 4000^2) - 4000
= 13793 - 4000
= 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

The length of this 3x and the width is 2x-3. This means that, to find the area, you need to multiply 3x and 2x-3.
Start by writing out this equation:
A=l*w
Then, plug in your given values:
A= 3x*2x-3 (you can also write it as A= 3*x*2*x-3)
Then, following the order of operations, you start by multiplying. This makes your equation become A = 6x^2 -3. (^2 means squared). It turns into this because 3 * 2 is 6 and x * x is x^2 and you still haven’t used the 3 yet.
After this, there is nothing more that you can do to simplify the equation. Therefore, the area is 6x^2 - 3.
