Will give extra points

4. 106.8142 5. 47.1239 6. 43.9823

Step-by-step explanation:

should be correct. its been a while since ive done circumfrence.

basically just used the formula c=2π(r)

and plugged in the radius

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
