When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units

alexira [117]

Answer:

r=1/π

Step-by-step explanation:

Area of the circle is defined as:

Area = πr²

Derivating both sides

$\frac{dA}{dr}$ =2πr

$\frac{dA}{dt}$ = $\frac{dA}{dr}$ x $\frac{dr}{dt}$ = 2πr $\frac{dr}{dt}$

If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have : $\frac{dA}{dt}$ =2 $\frac{dr}{dt}$

Therefore,

2πr $\frac{dr}{dt}$ = 2 $\frac{dr}{dt}$

r=1/π

The numbers 45 28 53 form a pythagorean triple true or false

GarryVolchara [31]

You can verify this by plugging the numbers into the Pythagorean theorem, $a^2+b^2=c^2$ , where c is the hypotenuse (the longest side, in this case 53).

So it would be: $28^2 + 45^2 = 53^2$
The equation is true.
2809 = 2809
