The diameter of the circle b is equal to the radius of circle a. if the radius of circle b is xy, what is the area of circle a?

Explanation:

Radius of circle B = xy

Diameter of circle B = 2xy (double the radius to get the diameter)

Radius of circle A = Diameter of circle B

Radius of circle A = 2xy

Use this radius to get the area of circle A

Area = pi*(Radius)^2

Area = pi*(2xy)^2

Area = pi*(2xy)*(2xy)

Area = pi*(2*2)*(x*x)*(y*y)

Area = pi*4*x^2*y^2

Area = 4pi*x^2y^2

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
