Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000).
We can look at 2 similar triangles.
1st triangle has legs: a vertical pole and its shadow, and
2nd triangle has legs legs : a child and his(her) shadow.
We can write a proportion:
height of a pole/height of a child= shadow of a pole/shadow of a child
8/4 = 5/shadow of a child
shadow of a child=(5*4)/8=5/2 ft

Step-by-step explanation:
<u><em>The picture of the question in the attached figure </em></u>
we know that
According to the <u><em>Perpendicular Tangent Theorem</em></u>, tangent lines are always perpendicular to a circle's radius at the point of intersection
That means ----> Triangles ODC and OEC are right triangles
In the right triangle OEC
we have
----> radius of the circle
Applying the Pythagorean Theorem
substitute the given values
