Given:
Height of the cylinder = 21 ft
Dimeter of the cylinder = 10 ft
To find:
The volume of the cylinder.
Solution:
We have,
Dimeter of the cylinder = 10 ft
So, radius is half of diameter, i.e., 5 ft.
Volume of the cylinder is
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height.
Putting [tex]\pi=3.14[/tex], r=5 and h=21, we get
[tex]V=(3.14)(5)^2(21)[/tex]
[tex]V=(3.14)(25)(21)[/tex]
[tex]V=1648.5[/tex]
Therefore, the volume of the cylinder is 1648.5 cubic ft.

Solve the system of equations using elimination
Answer:
(1, 3).
Step-by-step explanation:
x + 2y = 7
3x - 2y = -3
Adding the 2 equations will eliminate y:
4x = 4
x = 4/4
x = 1
Plug x = 1 into the first equation:
1 + 2y = 7
2y = 6
y = 3.

What is the equation of the line that passes through the point (−1,−1) and has a slope of −6?
Answer: y= -6x -7
Step-by-step explanation:
Point slope formula : y-y1=m(x-x1)
y- (-1)=-6(x- (-1))
y+1= -6(x+1)
y+1= -6x-6
y+1-1=-6x-6-1

A local yoga studio
charges a sign-up fee of
$55, plus $10 per class. A
second yoga studio
charges a sign-up fee of
$25 plus $12.50 per class.
A. Griffin
B. Gigi
Answer:
Let's call the first studio, yoga studio A.
Let's call the second studio, yoga studio B.
The equations:
Yoga Studio A: y=10x+55
Yoga Studio B: y=12.5x+25
So, for 12 classes:
Yoga Studio A: y=10(12)+55, y=175
Yoga Studio B: y=12.5(12)+25, y=175
These two numbers are equal, so Griffin is right.
For 10 classes:
Yoga Studio A: y=10(10)+55, y=155
Yoga Studio B: y=12.5(10)+25, y=150.
These two numbers are not equal, so Gigi is wrong.

A discount of 10 percent was given. If a further discount of 10percent was given in the reduced price, calculate the total single discount given in the marked price .
Answer:
let marked price = x
on 10% discount, price= x-10%of x
=x-(10x/100)
=x-(x/10)
=9x/10
on further 10% discount, total discount = 10% of 9x/10
=10/100 * 9x/10
= 9x/100
= 9%of x
hence, the single discount given on marked price is 9%

Answer:
323.5 square inches
Step-by-step explanation:
The cereal box is not shown. However, the given details are enough to arrive at a solution
[tex]Length = 13.5in[/tex]
[tex]Width = 2.5in[/tex]

what is j+m, j times m and j divided by m
Answer:
j + m
jm
[tex]\frac{j}{m}[/tex]
Step-by-step explanation:
We have j and m and are asked to add, multiply and divide them both.
When it comes to adding, its all about like terms, if the terms are not alike meaning ending in the same variable they cannot be added.
Therefore j + m is equal to just j + m.
Now for multiplying, this is free rule, you can freely multiply any variable you want without reprecussion.
Therefore, j * m is equal to jm.
Now for dividing, this works like adding, where you can divide only if the terms are the same, since j and m are not the same. J divided by M is equal to [tex]\frac{j}{m}[/tex]
