Question

What is the equation line parallel to z-axis and which passes through (-8,1)

Answer 1

line is parallel to z axis

hence, its x and y coordinates won't change

since it's parallel to x axis and passes through (-8, 1)

its equation is

y = 1

Answer 2

Answer:

area = circumference

area = circumferenceπr^2 = 2πr

area = circumferenceπr^2 = 2πr r^2 = 2r

area = circumferenceπr^2 = 2πr r^2 = 2r r =2
