Ox puts spherical weights at the ends of
his bar. They have a radius of 5.5 inches.
What is the volume of each weight? (The
formula for the volume of a sphere is
4/31tr3.)

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

i think it is c hope that
