Question

Given: AB= 4
AD= 6
What is the length of BD?
2
4
6

Answer 1

BD=AD-AB=6-4=2

Explanation:

You have a line segment AD that measures 6 units

AB is part of it and it is 4 units

There is only one part left of AD and it is BD so you just find what's left of 6 if 4 is already spoken for.

Answer 2

For this case we have that the radius of the large circle is given by AD = 6, while the radius of the small circle is given by AB = 4. We want to know the length BD, that is, the difference of the radius of the big circle and the small one.

`BD = AD-AB = 6-4 = 2`

So,
`BD = 2`

Answer:

`BD = 2`
