Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi.​

C= 22    A= 121

Step-by-step explanation:

formulas: circumference: 2r   area:   diameter = 2r

22/2 = 11, so r = 11

circumference: 2r = * 2r    ->  22

area: = *    ->   121

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
