Use the image of the circle to identify the length of the radius, diameter, and circumference. leave all answers in terms of π when necessary.

Please look at the attachment for the figure of circle with radius, diameter,circumference labelled.

AB is the diameter

OB and OA are radii

Radius is half of the diameter or in other words diameter is double of radius.

And circumference is the outer line of the circle

the 3rd option is right

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
