Answer:
40,320.
Step-by-step explanation:
We are asked to find the number of ways in which 8 books could be arranged on a shelf.
The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.
Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.
So the 8 books can be arranged in
Therefore, 8 books could be arranged in 40,320 ways.
Area of canvas = total area of the cone = π r ( r + s )
r ⇒⇒⇒ radius
s = slant height
the base has 20 feet across ⇒⇒ diameter = 2 r = 20
r = 20/2 = 10 and s = 14
area = 10 * 3.14 ( 10 + 14 ) = 753.6 ≈ 754
The correct answer is the third
Answer:

Answer:
168
Step-by-step explanation:
Start by finding the whole prism's volume. 9 x 3 x 8 = 216 Then find the volume of the missing part. 8 x 6 x 1 = 48. Subtract the missing volume from the whole volume. 216 - 48 = 168
17×2= 34
76-34= 40
2x=40
x= 20
