A mistake was made. In the first and second line, you're supposed to distribute. Int the first half, the 4 was distributed to the 8 and the 7. In the second half the 6 was only given to the 3 and not the 4.
So a diameter is twice the radius The formula is: V = π(r^2)(h/3) the half of 300 is 150, so the radius is 150 V = π(150^2)(150/3) V = π(22500)(50) V is about <span>3534291.74</span>
