Answer:
Step-by-step explanation:
Diameter of the cylinder = 14 centimeters
to find the radius divide the diameter by 2
Radius of the cylinder = 14/2 = 7 centimeters
Volume of the cylinder = V = πr² h
to solve it =
V = 22/7 × 7² × h
the equation is V = (22/7 × 7² × h)cm³
in solving it will be V = 22/7 × 49h
V = 1078/7
V = 154cm²
To find the volume of a cylinder, start with the formula for the volume of a cylinder.
Volume = 
Notice that our cylinder has a radius of 7 and a height of 16. So we have
() (7)
(16)
Let's start by simplifying the exponents. 
≈ 49
() (49) (16)
49 × 16 = 784
We can add a unit so we have 784.

Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:
c=2.75
Answer:
<u>390.4 in.²</u>
Step-by-step explanation:
- Area of sector = πr² x θ/360
- Area = 22/7 x 64 x 70/360
- Area = 11 x 10 x 32 x 1/9
- Area = 320 x 11/9
- Area = 320 x 1.22
- Area = <u>390.4 in.²</u>
