Find the center and radius of the circle x2+y2=16

The standard form of the equation of a circle is

(

x

−

a

)

2

+

(

y

−

b

)

2

=

r

2

where (a,b) are the coords of the centre and r , the radius.

x

2

+

y

2

=

16

is in this form

with a = b = 0 and r = 4

hence this circle has centre at the origin (0,0) and radius 4

The intercepts will therefore be (± 4,0) and (0, ± 4 )

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
