Answer:
The height is approximately 5.4961507
Step-by-step explanation:
The volume of a right cylinder is
π · r² · h, where r is the radius and h is the height.
We know the radius and volume. We can figure out the height like so:

Now, we just substitute the known values in for their corresponding variables:

The height of the cylinder is approximately 5.4961507

Answer:
Step-by-step explanation:
So let the angles be 2x,3x,5x
∠A + ∠B + ∠C + ∠C = 360
[Sum of all the angles of a quadrilateral ]
⇒2x+3x+5x+130=360
⇒10x = 360 -130
⇒x = 23
The angles are ,
∠A = 2x = 2×23 = 46
∠B = 3x = 3×23 = 69
∠C = 5x = 5×23=115
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.
