Step-by-step explanation:
From the picture provided, we are shown either the radius or diameter for a circle as the question. We need to find the area and the circumference of each question and match them up.
Diameter= straight line that passes through the center of the circle
Radius = 1/2 diameter
Area of Circle : [tex]\pi r^{2}[/tex]
Circumference of Circle: [tex]2\pi r[/tex] or [tex]\pi d[/tex] (2r=d)
Where r = radius, d = diameter, and π can be abbreviated to 3.14
Now to find each value just plug in the values of radius or diameter into the formulas and match them up to the area and the circumference.
