Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 centimeters. Round to the nearest tenth.
*there is no diagram*
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
This is due please help ASAP

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

4. If the base of a parallelogram is 61 m and the area is 645 m2, what is the height of the parallelogram
Answer:
10.57 m
Step-by-step explanation:
Let the height of the parallelogram be x m
Area of the parallelogram = base*height
645 = (61 * x ) m
x = 645/61
= 10.57 m
Hope this helps
Height of parallelogram = 10.57m
Given,
Base of parallelogram = 61 m
Area of parallelogram = 645 m²
Now, according to formula
Area of parallelogram = Base × Height
Substitute the given values in the formula,
645 = 61 × height
Height = 10.57 m
Hence, the height of the parallelogram with area 645m² and base 61 m is 10.57 m .

The sum of the digits of a two-digit number is 5. If nine is subtracted from the number, the digits will be reversed. Find the number.
If the tens digit is x, then the equation is:
The number is:
Answer: 32
Step-by-step explanation:
The only numbers that can have 2 digits and two of which equal to five can only be:
3+2
2+3
4+1
1+4
So the numbers are: 41,14,23, and 32.
41-9=32
14-9=5
23-9=14
32-9=23
Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
