The radius of a sphere is 18 feet. What is the surface area of the Recall the formula SA-4912. 72 57 square feet 144, square feet 1,296 square feet 5.184 square feet​

4.

step-by-step explanation:

it have the same area.brainliest

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.

t hope this
