Now that you've plugged r 3, or 1, into the equation, you can multiply this result by 4/3 to continue plugging in to the equation, V = ⁴⁄₃πr³. 4/3 x 1 = 4/3. Now, the equation will read V = ⁴⁄₃ x π x 1, or V = ⁴⁄₃π. [7] 5. Multiply the equation by π. This is the last step to finding the volume of a sphere.

Find the radius of the ball by first measuring the diameter (distance of a straight line through the ball at the widest part). Divide the diameter by 2; this gives the radius of your ball. Calculate the volume of the ball by plugging the radius into the equation for the volume of a sphere. Suppose the ball bearing has a radius of 0.01 meter (m).

According to the law of conservation of momentum, total momentum must be conserved. The final momentum of the first object is equal to 8 kg * 4 m/s = 32 N·s. To ensure no losses, the second object must have momentum equal to 80 N·s - 32 N·s = 48 N·s, so its speed is equal to 48 Ns / 4 kg = 12 m/s.
