This is a geometric sequence as each term is a constant ratio of the previous term, called the common ratio...

2a^2b/2a=(2a^3b^2)/(2a^2b)=ab and the first term is 2a

So the rule is:

a(n)=2a(ab)^(n-1)

a(6)=2a(ab)^5=2a^6(b^5)

We cannot know for sure if this series is infinite or not.  It would depend on what the values of a and b were.

If EITHER a^2 or b^2 is less than one the series would be finite (and technically a sequence and not a series),and a sum could be found.  If a^2 AND b^2 are greater than one it is an infinite series whos sum diverges....

The sequence is infinite  because  the exponents   2 ,3 ,4 ,... go on infinitely.

That next number in the equence is obtained by multiplying each term by ab.

the sixth term is   2a^(6)b^(5)

The area of a circle is 9pi cm². Find its radius. <br>Please do this question with full solution:)​
kirill115 [55]

Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

A = \pi r^2

Where "r" represents the radius of the circle. We can substitute the given value for Area into the equation to solve for the radius.

<h3>Solve for Radius</h3>

A=\pi r^2\\9\pi = \pi r^2

Divide both sides by π

9=r^2

Take the square root of both sides

\sqrt9=\sqrt {r^2}\\r=3

The radius of the circle is 3 cm.
