Well first you have to figure out what 25* 16 is, 400 and then you have to find what mulitplies to get 400 and adds up to get 40 and when you find the answer to that then you just GCF it.
I assume you're looking for the sum.
I would use the null property to eliminate 0
34+0+18+26
=34+18+26
then use commutativity to rearrange
=34+26 + 18
Add 34+26=60
=60+18
=78
So the amount needed=area of circle times height
area formula=pi times radius^2
height=3/4
so
pi=aprox 3.14
radius=7
3.14 times 7^2
3.14 times 49
153.86
times 3/4
115.395 in^3
answer is 115.4 cubic inches
