Step-by-step explanation:
The surface area of a cylinder is given as;
where r = radius
h = height
The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:
40 / 2 = 20 feet
The surface area is therefore:
The surface area of the cylinder is .
Answer:
h = 6
Step-by-step explanation:
Given the 2 equations
- 3x + 4y = - 30 → (1)
9x + 5y = 39 → (2)
We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations
Multiply (1) by 5 and (2) by - 4
- 15x + 20y = - 150 → (3)
- 36x - 20y = - 156 → (4)
Add (3) and (4) term by term thus eliminating y
- 51x = - 306 ( divide both sides by - 51 )
x = h = 6
The price per ounce for the 14.2 ounce bottle is $0.28. The price per ounce for the 33.9 ounce bottle is $0.29. Therefore, the 14.2 ounce bottle of shampoo Is the better buy.
You take the total price of the shampoo bottle and divide it by how many ounces there are to get the price per ounce.
