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

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

i think the answer is b.

step-by-step explanation:

not 100% sure though.
