Inverse equation t=120r/r+120 R=???

Komok [63]

9514 1404 393

Answer:

r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

$t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}$

What is the surface area of the cylinder with height 6 ft and radius 6 ft? Round your

Paul [167]

The surface area of this cylinder to the nearest thousandth is equal to 452.448 square feet.

<u>Given the following data:</u>

Height of cylinder = 6 ft.

Radius of cylinder = 6 ft.

To calculate the surface area of this cylinder to the nearest thousandth:

<h3>How to calculate surface area.</h3>

Mathematically, the surface area (SA) of a cylinder is given by this formula:

$SA = 2\pi rh + 2\pi r^2$

<u>Where:</u>

h is the height.

r is the radius.

Substituting the given parameters into the formula, we have;

$SA = 2 \times 3.142 \times 6 \times 6 + 2 \times 3.142 \times 6^2\\\\SA = 226.224 + 226.224$

SA = 452.448 square feet.
