Given that:
Diameter = 5 cm
which means,
Radius= \frac{diameter}{2} = \frac{5}{2} = 2.5 cm (radius is half the diameter)
and Height = 2 cm
We can assume that the shape is cylindrical 

Formula of the Surface Area of a Cylinder
=2\pir² + 2\pirh
=2\pi(2.5)² + 2\pi(2.5)(2)
=12.5\pi + 10\pi
=22.5\pi cm² (in terms of \pi)
=70.69 cm² ≈ 70.7 cm²

A tile factory earns money by charging a flat fee for delivery and a sales price of $0.25 per tile. One customer paid a
ddd [48]

Answer: R(x) = 0.25x + 500

Flat fee is computed by:

The sales price of each tile is 0.25 and the customer only bought 10,000 tiles.

So, $0.25 x 10,000 = $2500

So the total sales price per tile sold was $2,500.

The buyer paid $3,000, so the flat fee was included there.

So, $3,000 - $2,500 = $500

So the flat fee was $500.

~

The revenue function is the total income from producing the units. And it has a equation of: R(x) = price per unit x number of units sold plus any fee that is included

So the function describing the revenue of the tile from this sale is:

R(x) = 0.25x + 500

18% of 90 is what number?
bearhunter [10]
<span>90/x=100/18</span>
<span>(90/x)*x=(100/18)*x       - </span> multiply both sides of the equation by x
<span>90=5.55555555556*x       - </span>divide both sides of the equation by (5.55555555556) to get x
<span>90/5.55555555556=x </span>
<span>16.2=x </span>
<span>x=16.2</span>
<span>18% of 90=16.2
