Area = 64π

Circumference = 2πr or πd

diameter = 16 (Diameter times π = 16π so this is obvious)

radius = diameter divided by 2 = 8

Area = πr², so π times 8² = π times 64 = 64π

How many variables should an experiment test at a time
Llana [10]

Answer:

One

Step-by-step explanation:

<em>Hope this helps,</em>
