<h3>Explanation:</h3>The shortest distance from P to the circle is along the line between P and the center of the circle. That line is the hypotenuse of the right triangle whose legs are PQ and QC (where C is the circle center).
The Pythagorean theorem tells you
... PC² = PQ² +QC²
... PC² = 13² +9² = 250
... PC = √250 = 5√10 ≈ 15.8114 . . . . inches
The distance from P to the circle is 9 in less than this, so is
... 15.8114 - 9 = 6.8114 ≈ 6.8 . . . . inches
Answer
Find out the how many ping pong balls would fit inside the Earth.
To prove
Let us assume that the number of ping pong would fit inside the Earth be x.
As given
A ping pong ball has a volume of approximately 3.4 cm³.
The Earth has a volume of approximately cm³ .
Than the equation becomes
(approx)
Therefore in (approx) ping pong balls would fit inside the Earth.
