Answer:
-1x+10
Step-by-step explanation:
Step-by-step explanation:
Mean of the origibal set = 20
No. of terms = 10
Sum = Mean x No. of terms
= 20 x 10 = 200
The sum of additional numbers to make the new set of observstion is 4 + 8 + 12...... + 40 = 220
New Sum = 200 + 220 = 420
The no of terms stay the same
New Mean = New Sum/ N
= 420/10
= 42
Answer:

Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of

Substituting the formula for A into formula for volume then

Substituting 8ft for r and 20 ft for h then

Rounded off to the nearest tenths, the volume is equivalent to
