The point (0,5) lies on a circle that is centered at the
origin. Does (-3,-4) also lie on the circle?
1. Identify the radius from the graph.
= units
2. Determine the distance from the center to
(-3,-4) using the distance formula.
distance = units
3. Compare the radius to the distance. Does the
point (-3,-4) also lie on the circle?

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.

the answer is b 4pi/3

got it down chief.
