Answer:113.1
Step-by-step explanation: The equation for volume of a sphere is (4/3)πr^3
r=.5 d so r=3. You plug it in and get (4/3)π * 27 because 3*3*3=27. From there you just multiply everything together because there is no adding subtracting or dividing left to do. You can then plug in plug in the equation (4/3)π * 27 into your calculator.
