1. recall some formulas:
Volume of Sphere = (4/3)*pi*(r^3)
Surface Area of Sphere = 4*pi*(r^2)

since we do not know the value of radius, we get it from the surface area:
804 = 4*pi*r^2
now solve for r with your calculator~
after solving r, plug in this value to the formula for volume~

hope this helps~ :)
