From these three rows number, we can find out that the second row is 8 more chairs than first row and third row is also 8 more than second row. Then we can say that the number of chairs(x)=[the row number(n)-1]*8+6=8n-2. The total number S=[6+(8n-2)]*n/2. When n=7, S=210.

Veseljchak [2.6K]

Answer:

D. 267.9 in3

Step-by-step explanation:

So we know the diameter is 16 inches.

So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4

Now we need to find the volume.

V= 4/3 times 3.14 times 4^3= 268.08

So we would need to round which would give us 267.9 in3.

Therefore the answer is the D. 267.9 in3.

I hope this helps!!!
