Find the circumference of the circle.
2 answers:
As we know the CIRCUMFERENCE:- 2πr
Here r belongs to radius which is equals to = diameter/ 2
Here in the given picture the diameter is 14 so the radius will be 7 .
Now CIRCUMFERENCE = 2× π × 7
= 14π
But we habe to findonly the number which is suitable for the given box so there will be 14 in the box
So 14 is the correct answer .

To solve this question we will make use of the "Triangle Angle Bisector Theorem", which states that, "An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle."
Thus, in our question, we will have:
The above equation can be rearranged as:
...(Equation 1)
If we have a proper look at the denominator which is , we note that in
,
Thus, (Equation 1) wil give us:
<u>Therefore, LB= 12 feet</u>
