For this case we must indicate the correct sign between the following numbers:

We have to:

So, we have to 
Answer:

13.1 an hour, 34 hours a week
13.1 x 34 = 445.4 a week
to find out how many weeks, divide 4300 and 445.4 which is 9.65 weeks, which is technically 10 weeks
it would take 10 weeks to earn 4300

If Sa=2πrh+2π
v=π
then the surface area is π
and volume is
(rh-2h)/2r.
Given Sa=2πrh+2π
=π
.
We have to find surface area and volume from the given expression.
Volume is basically amount of substance a container can hold in its capacity.
First we will find the value of v from the expression. Because they are in equal to each other, we can easily find the value of v.
2πrh+2π
v=π
h
Keeping the term containing v at left side and take all other to right side.
2π
v=π
-2πrh
v=(π
h-2πrh)/2π
v=π
/2π
-2πrh/2π
v=h/2-h/r
v=h(r-2)/2r
Put the value of v in Sa=2πrh+2π
Sa=2πrh+2π
*h(r-2)/2r
=2πrh+2πrh(r-2)/2
=2πrh+πrh(r-2)
=2πrh+π
h-2πrh
=π
h
Hence surface area is π
h and volume is h(r-2)/2.
