Answer:
YES
Step-by-step explanation:
Any line that is tangent to a circle is always perpendicular to the radius of the circle, forming a right angle at the point of tangency.
Therefore, ∆BAC is a right triangle if it satisfy the pythagorean triple rule which says that c² = b² + a²
Where,
c = the hypotenuse = 30
b = 24
a = 2(9) = 18
Thus:
30² = 24² + 9²
900 = 900 (this is true)
Therefore, line AB is tangent to circle O.
The answer is YES
Let, initial side is a.
When side is n times long, new side na.
Initial volume, 
Final volume, 
Change in volume, 
For, n = 2 :

n = 3 :

n = 10 :

Hence, this is the required solution.
Answer:
the answer is 611.2
how,-3.3x
611.2
=6
there before 614.2 there come always+if there is nothing
then,there is- before-3.3x then rule=
<h3>- + +=-</h3>
so we have to substract it
