jour brought to you by circles whenever you need him

to be around All right A circle has an area

of sixteen pi square units Not blank of the circle

is eight units The what of the circle is a

unit And why is it bragging about it to the
- 00:26
other circle It's Not cool Well we've got three options
- 00:29
Radius diameter fan circumference Hard to find any of these
- 00:36
three You have to start by finding the radius So
- 00:39
let's start by finding the radius area of a circle
- 00:43
is always pi Times are square with our being radius
- 00:47
Okay so we know that sixteen pie which were given
- 00:50
in the problem equals pi r squared But we confide
- 00:54
both sides My pie to get that sixteen equals r
- 00:58
squared and we'll take square root of sixteen which is
- 01:02
four Oh yeah Four equals are well for eight Unless
- 01:08
there's something seriously screwed up about her finger We know
- 01:11
that a radius is half of a diameter and force
- 01:15
half of eight though putting two and two together Or
- 01:17
in this case for for we can deduce that the
- 01:20
circle's diameter eyes eight units Oh although it sure would 00:01:25.714 --> [endTime] be nice That learned to show some humility Yeah
