Answer:
Step-by-step explanation:
GIVEN: Suppose you want to make a cylindrical pen for your cat to play in (with open top) and you want the volume to be cubic feet. Suppose the material for the side costs per square foot, and the material for the bottom costs per square foot.
TO FIND: What are the dimensions of the pen that minimize the cost of building it.
SOLUTION:
Let height and radius of pen be
Volume
total cost of building cylindrical pen
for minimizing cost , putting
Hence the radius and height of cylindrical pen are and respectively.
Yes, that seems like the right answer. So no they dont have enough paint to finish the job on Wednesday.
Answer:
Step-by-step explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³
Answer:
ANSWER = X = 4ac - 2b / 3ac
Step-by-step explanation:
Let's solve for x.
3a x + 2b / c = 4a
Step 1: Multiply both sides by c.
3acx + 2b = 4ac
Step 2: Add -2b to both sides.
3acx + 2b + −2b = 4ac + −2b
3acx = 4ac − 2b
Step 3: Divide both sides by 3ac.
3acx / 3ac = 4ac − 2b / 3ac
Answer = x = 4ac − 2b / 3ac

Answer:
Solution given:
perpendicular [P]=80ft
base[B]=18ft
hypotenuse [H]=?
By using Pythagoras law
H²=P²+B²
H²=80²+18²
