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

seems like d

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
