<PRE><B>Question 892608</B>
A = pi*r^2


289pi = pi*r^2


289 = r^2


r^2 = 289


r = sqrt(289)


r = 17


The radius of this sphere is 17 feet.


-------------------------------------------------------


Surface Area:


SA = 4pi*r^2


SA = 4pi*17^2


SA = 1156pi


The exact surface area of this sphere is 1156pi


-------------------------------------------------------


Volume:


V = (4/3)pi*r^3


V = (4/3)pi*17^3


V = (19652/3)pi


The exact volume of this sphere is (19652/3)pi</PRE>
