Area of circle.

[a.m]

A circle of area A passes through the points (8,0) and (0,6). Then we must have :

a. A < 25 pi
b. A >= 25 pi
c. A = 100 pi
d. None of the above.

[AJ]

B

distance between these points is 10..

so diameter is >= 10
so.. r>=5
... r^2 >= 25

and A=pie r^2 >= 25 pie

thank you !
