It should be 126in 10.5ft and 3.5 yards. First convert to inches then divide by 12 for feet then divide by 3 for yards.
See the attachment for answer:
V≈<span>1436.76 units cube (sphere)
</span>V=πr^2<span>h (cylinder)
r=7
h=14
</span>V≈2155.13 <span>units cube (cylinder) </span>
The first polynomial is
The other polynomial is
Now to add polynomials we must add or subtract like terms
Adding them we have
Here
So we add then
We get
The addition of the polynomial is
