Step-by-step explanation:
By interior angle sum theorem of a triangle.

263.76 cm is the minimum amount of paper she will need to wrap the entire container.
<u>Step-by-step explanation:</u>
As we know that the equation for surface area of a cylinder,
Surface area of cylinder = 
Where,
r - the radius of the cylinder. Here given diameter (D) as 6. So,

h - the height of the cylinder (given as 11 cm). The value for pi = 3.14. Now, calculate the surface area of the cylinder as

A = 56.52+ 207.24 = 263.76 cm
Answer:
31.000
Step-by-step explanation:
32.4-1.40=31.0000
Answer:
The sentence
"The Number of Chem textbooks sold is 86 less than the number of History textbooks"
This seems to be the confusing part.
Now look at it this way...
'If CHM text is 86 less than History text... It also means that History Text is 86 More than CHM'
This expression can be written as
Let History Text be "H"
Let CHM text be "C"
C - 86 = H
or
C=H + 86.......1
First line of this question is interpreted thus
H + C = 326.......2
From eqn 1... C=H+86
Substitute into Eqn 2
H + C=326
H + (H+86)=326
H+H=326-86
2H=240
H=240/2
H=120.
C=H+86
C=120+86
C=206.
This answer is correct... Why?
The key statement says .. The Number of CHM sold is 86 less than History...
Also interpreted as
The Number of CHM – 86 = History
206 - 86 =120.
Have a great day!!!
