Circle D is shown. Line segment C D is a radius with length 18 centimeters. Which statements are true regarding the area of circle D? Select two options. The area of the circle depends on the square of the radius. The area of circle D is 36Pi centimeters squared. The area of circle D is 324Pi centimeters squared The area of the circle depends on the square of pi. The area of the circle depends on the central angle.

I just took the test, it's 1 and 3

Step-by-step explanation:

The answer is 1) The area of the circle depends on the square of the radius.

and 3) The area of circle D is 324Pi centimeters squared.

Step-by-step explanation:

The reason 3) is the answer is because when you are finding the area of the circle the equation is...

Area = Pi r^2      meaning that that the equation would be A=3.14(18^2)

which equals...

324 Pi cm^2

step-by-step explanation:

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.
