Answer:
<h2>A. x = 1</h2>
Step-by-step explanation:

Answer:
The approximate height of the paint can is 8.2 in
Step-by-step explanation:
we know that
The volume of the cylinder ( can of paint) is equal to

we have



Substitute the values and solve for h
231=(3.14)(3)^{2} h
h=231/(3.14*9)=8.2 in
I'm pretty sure to solve this all you do is subtract 77.95 - 75.65, which would be 2.30. Hope that helps!
Sorry I don't what the answer would be for A. But B would be (3,13)
Vsphere=(4/3)pir³
d/2=r
d=6.2
6.2/2=r=3.1
vsphere=(4/3)pi3.1³
vsphere=(4/3)pi29.791
Vsphere=124.72498666666666666666666666667
answer is 124.72498666666666666666666666667 cubic feet
or rounded to neares whole, 125 square feet
