Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by circles whenever you need him

00:08

to be around All right A circle has an area

00:13

of sixteen pi square units Not blank of the circle

00:17

is eight units The what of the circle is a

00:21

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
