Answer:
6.28 gallons
Step-by-step explanation:
first we need to find the area of a half sphere, and then find how much paint will be needed for that area.
The area of a sphere:
thus, the area of half a sphere is:
we know that the radius is:
we substitute this to find the area of the half sphere (the area they need to paint):
now the question is how many gallons of paint are needed to paint 2,513.27 square feet.
We are told that 1 gallon covers 400 square feet
thus, we must divide 2,513.27 by 400:
6.28 gallons of paint are needed.
Use the rational root theorem:
